How can we find the
output of recursion program in quicker way in c programming language


(1)What will be output of following c recursion program?




#include
int main(){

    int x,num=4;

    x=call(num);

    printf("%d",x);

    return 0;



}

int call(int num){

    static int x=1,y;

    if(num>0){

         x=x*num;

         y=call(num-1)+call(num-2);

    }

    return x;

Nesting of function call in C programming

Nesting of function call in c programming


If we are calling any function inside another function call is known as nesting
function call. Sometime it converts a difficult program in easy one.



For example:



Try to find out
maximum number among the five different integers without using nested function
call.

nested function

Function overloading in c

C doesn’t support function overloading. In c it is not possible to declare two function of same name but different signatures like number of parameters, data type of parameters, order of parameter etc.

For example:

int display(int x){

    return x;

}

int display(void){

    return 1;

}

void main(){

    int x,y;

    x=dispaly();

    y=display(1);

    printf("%d  %d",x,y);

    getch();
