- Write a program in C that initializes one each of the basic C data types and then print them out. Don't forget pointer. Also print the size of each.Discussion: Files with .h extension are called header files in C. These header files generally contain function declarations which we can be used in main C program, like for e.g. to include stdio.h in C program to use function printf() Exercise 1. C-Program to Create your own Header File Step 1 : Type this Code int add(int a,int b) { int sum; sum= a+b; return sum; } In this Code write only the function definition as you write in General C Program Step 2 : Save Code Save Above Code with [.h ] Extension . Let the name of our header file be myhead [ myhead.h ] Compile Code if required. Step 3 : Write Main Program #include<stdio.h> #include"myhead.h" int main() { int num1 = 10, num2 = 10, num3; num3 = add(num1, num2); printf("Addition of Two numbers : %d", num3); } Instead of writing < myhead.h>; use this terminology “myhead.h” All the Functions defined in the myhead.h header file are now ready for use . Directly call function add(); [ Provide proper…Design a modular solution, using a structure chart , and then write a C program based on the structure chart solution that solves the following question. Show the flow of data on your structure chart; in the program, this is achieved by parameter passing and function return data. Data for your program comes from an input file called infile.txt. Each line in the data file has a person’s first name (one word) and an age (separated by a space). There can be up to 10 lines in the data file, and there may be names that are the same (in this case, it can be assumed that the record is for that same person). An example of one line is: Tony 30 Your program reads the data into a data structure, which consists of an array of records (i.e. array of C structs). Thus, the program would need to define a suitable struct, and create an array of these structs. Once the data is read in and stored in the data structure the program closes the input file, and then determines if there are any repeated…
