Herry bhai your way of explaining the actual perameter and formal perameter is really superb .

Thanks harry bhai mere college ke assignment me tha ye question
#include
int interchange(int *x,int*y){
int z;
z = *x; //stores num1 value in another variable
*x = *y; //stores num2 value in num1
*y = z; // stores num1 value in num2
}
int main(){
int a,b;
printf("Enter the value of num1 :
");
scanf("%d",&a);
printf("Enter the value of num2 :
");
scanf("%d",&b);
printf("num1 = %d
num2 = %d
",a,b);
interchange(&a,&b);
printf("After interchanging
");
printf("num1 = %d
num2 = %d
",a,b);
}

[@atifmalik8012]

Call by reference example in this i changed actual value of x and y by using pointer
#include
float func1(float *a,float *b){
*a = 1.6;
*b = 1.0;
}
int main(){
float x = 12.0,y=6.0;
printf(" x before calling %f
y before calling %f
",x,y);
float d = func1(&x,&y);
printf(" x after calling %f
y after calling %f
",x,y);
}

its absolutely wrong bro ..if you print the values of a and b it should be 7 and 1,,,whereas u are printing temp1 and temp2....the actual arguments a,b should be changed ,,,

Bhai mujhe ek chij nahi samajh me nahi aa raha hai ki
Call by value or call by refrence dono ke kya writing difference hai

[@shivamdaund181]

By reference mai address use krte hai isliye usme pointers aur address dene ke liye & use krte hai
