Question

I am trying to create a function that increments x 4 times, then my program prints the results. For some reason my function is not changing the value of x. It just stays the same.

#include <stdio.h>

int Incrementx4Times(int x) // This function increments user inputted value
{
int count;  
//increments 4 different ways  
x++;
x=x + 1;
++x;
x += 1;
return x;
}

void main(void)
{
int x;
printf("x? "); scanf("%d", &x);
printf("x = %d\n", x);
Incrementx4Times(x); //Call funtion
printf("The final answer is %i", x);
}

#include <stdio.h>

int Incrementx4Times(int x) // This function increments user inputted value
{
    int count;
//increments 4 different ways  
    x++;
    x = x + 1;
    ++x;
    x += 1;
    return x;
}

void main(void) {
    int x;
    printf("x? ");
    scanf("%d", &x);
    printf("x = %d
", x);
    x = Incrementx4Times(x); //Call funtion
    printf("The final answer is %i", x);
}
