How to pass parameters in the function in C

In c we can pass the parameters in a function in two different ways.



(a)Pass by value: In this approach we pass copy of actual variables in function as a parameter. Hence any modification on parameters inside the function will not reflect in the actual variable. For example:



#include

int main(){

    int a=5,b=10;

    swap(a,b);

    printf("%d      %d",a,b);

    return 0;

}
