In this program, we are going to share a c program to illustrate pass by value. If you are a beginner and want to start learning the C programming, then keep your close attention in this tutorial as I am going to share a c program to illustrate pass by value with the output.
We have designed this program for beginners for learning purpose. Copy below c program and execute it with c compiler to see the output of the program.
void swap(int a, int b)
temp = a;
a = b;
b = temp;
int num1 = 10, num2 = 20;
printf("Before swapping num1 = %d num2 = %d\n", num1, num2);
printf("After swapping num1 = %d num2 = %d \n", num2, num1);
Before swapping num1 = 10 num2 = 20
After swapping num1 = 20 num2 = 10
