Write and explain the following types of functions with the help of an example program for each (i) Function with no arguments and no return value. (ii) Function with arguments and no return value

hello Write and explain the following types of functions with the help of an example program for each  (i) Function with no arguments and no return value. (ii) Function with arguments and no return value. ANS-    1:  Function with no arguments and no return value: OUTPUT               In this type the function has no arguments, it doesn't receive any data from the calling function. Similarly it doesn't return any value, the calling function doesn't receive any data from called function.  So there's no digital communication between calling function and called function. #include<stdio.h> #include<conio.h> void sum(); void main() {        clrscr();     sum();     getch(); } void sum() {     int a,b;     printf(”Enter any two numbers:”);     scanf("%d%d",&a,&b);     printf(”sum= %d”,a+b); } In this function no return and no argument means create sum function. no any return type, void is no return type data type.  all processing is done inside

Question :- Using pointers, write a C program to swap the values of two variables. #include <stdio.h> #include<conio.h>   void main() {    int first_value, second_value, *first_pointer, *second_pointer, temp;      printf("Enter the value of First Value and Second Value\n");    scanf("%d%d", &first_value, &second_value);      printf("Before Swapping\nfirst_value = %d\nsecond_value = %d\n", first_value, second_value);      first_pointer = &first_value;    second_pointer = &second_value;      temp = *second_pointer;    *second_pointer = *first_pointer;    *first_pointer = temp;      printf("After Swapping\nfirst_value = %d\nsecond_value = %d\n", first_value, second_value);      getch(); } write a C program to swap the values of two variables Using pointers  int first_value, second_value, *first_pointer, *second_pointer, temp; it's declare variable two variable first_value and second_value it using to input a value by
