C program to use similar variables in different functions

In this tutorial, we are going to write a C program to show how similar variable names can be used in different functions in C Programming with practical program code and step-by-step full complete explanation.

C program to use similar variables in different functions.

 
#include<stdio.h>
#include<conio.h>

void fun();
void main()
{
    int b=10,c=5;

    printf("In main() B=%d C=%d",b,c);
    fun();
}

void fun()
{
    int b=20,c=10;
    printf("In fun() B=%d C=%d",b,c);
}

Output

 
In main() B=10 C=5
In fun() B=20 C=10
