Solution for Exercise 10-8

ex1008

#include <stdio.h>

void graph(int count,char ch);

int main()
{
    int value;

    value = 2;

    while(value<=64)
    {
        graph(value,'=');
        printf("Value is %d\n",value);
        value = value * 2;
    }
    return(0);
}

void graph(int count,char ch)
{
    int x;

    for(x=0;x<count;x=x+1)
        putchar(ch);
    putchar('\n');
}

Notes

* If you make a mistake, it's probably that you forgot to modify the graph() statement in Line 13, which now requires two arguments.

* You may have also forgotten to re-prototype the graph() function. Oops.

* You get For Dummies bonus credits if you use the same variable name as I did in the graph() function, as well as the same character in Line 13.
