void salaryhike(int *var, int b)
{
*var = *var+b;
}

salaryhike(&salary, bonus);
printf("Final salary: %d", salary);
return 0;
}
Example 2: how to use a pointer as a parameter in c
#include <stdio.h>
#include <stdlib.h>
#include <math.h>
void add(int* a, int* b, int* c)
{
*c = *a + *b;
}
int main()
{
int a, b, c;
a = 3;
b = 5;
add(&a, &b, &c);
