Methods of Calling Function?

[jahanzab niazi]

Please tell me any two methods of calling the function?

[Peter87]

if you have function called foo that takes no arguments you call it by writing foo().

[eypros]

What exactly do you ask? Can you be more specific?

Call by value:

#include <stdio.h>
#include <stdlib.h>

void swap(int i, int j); //wrong example

int main(){
	int i, j;
	i = 5;
	j = 9;
	swap(i, j); //call by value
	printf("i=%d j=%d\n", i, j);
	system("pause");
	return 0;
}

void swap(int i, int j){
	int temp;
	temp = i;
	i = j;
	j = temp;
}

Call by address:

#include <stdio.h>
#include <stdlib.h>

void swap(int *i, int *j); //correct example

int main(){
	int i, j;
	i = 5;
	j = 9;
	swap(&i, &j); //call by address
	printf("i=%d j=%d\n", i, j);
	system("pause");
	return 0;
}

void swap(int *i, int *j){
	int temp;
	temp = *i;
	*i = *j;
	*j = temp;
}
