Build the C program from the main routine described below:
int main(int argc, char* argv[])
{
while(1)
return 0;
}
The program must count how many times the user
sends the SIGINT signal to the process in
execution. When the signal receives a SIGTSTP
(Ctl-Z), it should print the number of signals
SIGINT he received. after having received
3 SIGINT's, the program must “invite” the
user to exit (“Really exit (Y/n)?”). If the
user does not respond within 20 sec., the program
ends alone.

- Semaphores can be used as a general-purpose synchronization tool. Suppose statement B in process P1 can be executed only after statement A in P2. Use a semaphore named S to show how such synchronization is to be carried out, by showing the structure of both P1 and P2. You need to decide the initial value of S to synchronize that wayWrite a program in C++ to asked user to input positive integers toprocess count, maximum, minimum, and average or terminate theprocess with -1.Write a parallel program using MPI (and not OpeMP) to accomplish the same as the following serial program. For the following serial program the user enters a line and the program outputs the number of occurrences of each printable character (but not the space or tab character). For the parallel program if we have p processes we should divide the line into p segments and let each process counts the characters of its segment#include<stdio.h>#include<stdlib.h>#include <string.h>#define ASCIIs 127 //ASCII characters from 0 to 127define atmost 1000char letters[atmost + 1]; //Extra location for the string terminator '\0'int total_count[ASCIIs];void find(int count[],int start, int end);int main(){ int i, processes, n, start, end; int count[ASCIIs], my_rank, segment, p;printf("Enter a line not larger than 1000 characters.\n");fgets(letters, atmost,stdin);printf("How many segments?: ");scanf("%d", &processes);//To make the length of the divisible by…
- Write program in which one process sends a word and a character separated by space using named pipe and second process finds the occurrences of that particular character in word and responds with count of that character. Input sample: pipe p Output sample: 2Computer Science Consider the following C++ pseudo code. The code contains names of MIPS registers rather than C++ variables. It is not pure C++ but the concepts are clear (e.g., calling a function with integer arguments and returning integer results). int a(){ Int $a1, $a2, $v1, $s0; $a1 = 3; $a2 = 4; $v1 = b($a1, $a2); $s0 = $s0+$v1 //Printout $s0 and exit (not shown) } int b(int $a1, int $a2){ Int $v0, $t0; $t0 = 5; $v0 = c($a1, $a2) $v0 = $t0 + $v0 Return($v0)} int c(int $a1, int $a2){ Int $v0, $s0; $s0 = 6; $v0 = $s0 +$a1 + $a2; Return($v0) } Convert b(), and only b(), to MIPS assembly language. Take into account any frame prepared and being filled up by the modules, a(), b(), and c(). The code for b() should reveal the relevant frames. Assume that the stack grows down in addresses and that the stack pointer points to the current data at the top of the stack.Write and simulate a MIPS assembly-language routine that: 1. Prints your group number, for example “Group 1”, 2. Computes the dot product of two vectors, A_vec and B_vec, as described in Lab 4 of the Lab Manual, 3. Stores the result at memory word DOTPROD, and 4. Prints the result preceded by the phrase: “The result of the dot product is: “. Your data segment should look like the following: .data group: .asciiz “\nGroup x” msg: .asciiz "\nThe result of the dot product is: " A_vec: .word x, 4, 20, 13, 3, 10, 5 B_vec: .word 4, 2, 1, 2, 5, 2, 4 n: .word 7 DOTPROD: .word 0 Replace each “x” with your group number.
- Write a MIPS procedure that takes as its three parameters the address of a zero-terminated string, a character c, and an integer n, and returns the number of distinct runs of consecutive instances of c in the string that are of length at least n. Also, write a simple main program to test your procedure. Your main program should input a string from the user (you may assume that the string has at most 20 characters), input the character and the integer, invoke your procedure, output the return value, and then terminate. For example, given the inputs “bbabbbbagbgbb”, “b”, and 2, the output should be 3. Your code must use the “standard” conventions covered in class for passing parameters and returning results. code in mipsIn C, both long x and int *y are 8-byte values. How can we can tell which one is which in the assembly compiled from the C? (I.e., what is true of one but not the other? If several answers seem correct, pick the most precise option.) A. x is stored in a register, y in memory B. x is modified using addq, y using addl C. x may be an argument to add but y won't be D. When an argument of mov, a register storing x will never be inside parentheses E. When an argument of mov, a register storing y will always be inside parenthesesModify the following program in lc-3 to get the input(numbers) from the keyboard and print the result to console. .ORIG x3000Loop LD R0, number1 ; load number1 into R0LDR R1, number2 ; load number2 into R1ST R2, SaveR2 ; save register R2LD R5, goSUB ; load address of SUB into R4JSRR R5 ; go to subroutine whose address in R5STR R3, result ; store resultLD R2, SaveR2 ; restore old value R2HALTnumber1 .FILL #10number2 .FILL # -8goSUB .FILL SUB ; initialize goSUB to address of SUBSaveR2 .BLKW #1; reserve space SaveR2 and SaveR3result .BLKW #1SUB NOT R1, R1ADD R2, R1, #1ADD R3, R0, R2RET.END
- Write the following c/c++ code into RISC-V assembly please. It has to follow the conventions about functions and stacks. void f(char* x, char* y) { char *srcPtr = x; char *dstPtr = y; if (strlen(x) > strlen(y) { srcPtr = y; dstPtr = x; } for (int i = 0; i < strlen(srcPtr); i++) { dstPtr[i] = srcPtr[i]; } }write the following questions a) Write an 8051 C program to send Hex values for ASCII characters of 0,1,2,3,4,5AB,C and D to port P1 b) Interface a 4X4 keyboard with 8086 using 8255, and write an ALP for detecting a key closure and return the key code in AL.
