(Signal Handling) Read the documentation for your compiler to determine what signals are supported by the signal-handling library (). Write a program that contains signal handlers for the standard signals SIGABRT and SIGINT. The program should test the trapping of these signals by calling function abort to generate a signal of type SIGABRT and by having the user type c ( C on OS X) to generate a signal of type SIGINT.
Mark the following statements as true or false. i. An identifier can be any sequence of digits and letters. ii. In C++, there is no difference between a reserved word and a predefined identifier. iii. A C++ identifier can start with a digit. iv. The operands of the modulus operator must be integers. v. If a = 4; and b = 3; then after the statement a = b; the value of b is still 3. vi. The result of a logical expression cannot be assigned to an int variable. vii. Every if statement must have a corresponding else. viii. The expression in the if statement: if (score = 30) grade = 'A'; always evaluates to true. ix. The expression: (ch >= 'A' && ch = 'Z'. x. The expression !(x > 0) is true only if x is a negative number.
Add a main function () to the code and organize it using mainline logic. You are also require to add variables, parameters and arguments in each function. def display_state_details(state_code,district_code): print(state_code,district_code,end="") def display_vechicle_number(vehicle_code,vehicle_number): print(vehicle_code,vehicle_number) state_code=input("Enter the state code:") district_code=int(input("Enter the district number:")) vehicle_code=input("Enter vehicle code:") vehicle_number=int(input("Enter the vehicle number:")) print("The genertaed licenses plate number is:") display_state_details(state_code,district_code) display_vehicle_number(vehicle_code,vehicle_number

(Conversion) a. Write a C++ program to convert meters to feet. The program should request the starting meter value, the number of conversions to be made, and the increment between metric values. The display should have appropriate headings and list the meters and the corresponding feet value. If the number of iterations is greater than 10, have your program substitute a default increment of 10. Use the relationship that 1 meter = 3.281 feet. b. Run the program written in Exercise 6a on a computer. Verify that your program begins at the correct starting meter value and contains the exact number of conversions specified in your input data. c. Modify the program written in Exercise 6a to request the starting meter value, the ending meter value, and the increment. Instead of the condition checking for a fixed count, the condition checks for the ending meter value. If the number of iterations is greater than 20, have your program substitute a default increment of (ending value - starting value) / 19.
1. Mark the following statements as true or false. a. An identifier must start with a letter and can be any sequence of characters. (1) b. In C++, there is no difference between a reserved word and a predefined identifier. (1) c. A C++ identifier cannot start with a digit. (1) d. The collating sequence of a character is its preset number in the character data set. (2) e. Only one of the operands of the modulus operator needs to be of type int. (3) f. If ; and ;, then after the statement ; the value of b is erased. (6) g. If the input is 7 and x is a variable of type int, then the statement ; assigns the value 7 to x. (6) h. In an output statement, the newline character may be a part of the string. (10) i. In C++, all variables must be initialized when they are declared. (7) j. In a mixed expression, all the operands are converted to floating-point numbers. (4) k. Suppose . After the statement ; executes, y is 5 and x is 6. (9) i. Suppose . After the statement ; executes, the value of a is still 5 because the value of the expression is not saved in another variable. (9)
Define a C++ language float literal using regular expression. A float literal in C language has an optional exponent part. If a float literal is written without exponent part, then it must have a decimal point which can appear at the start, at the end or in the middle of digits, as in following examples: 123.456 .456 456. If float literal is written with exponent, then decimal point in mantissa part is optional, and exponent is a whole number with optional sign, as in following examples: 123e78 123e+78 123e-78 123.456e78 .456e78 456.e78
