    error C2668: 'sqrt' : ambiguous call to overloaded function ???

    I'm using Microsoft Visual C++ and have this lab due in a couple hours......

    However, everytime I try to run it I keep getting "error C2668: 'sqrt' : ambiguous call to overloaded function", and for the life of me I cannot understand why......

    Any help would be greatly appreciated! Thanks!

    Code:
    #include <stdio.h>
    #include <math.h>
    
    int main(void)
    {
      
        int i, n;
        float s;
        
    
        printf("Enter an Integer: ");
        scanf("%d", &n); /* obtain number */
        	
        if (n>0)
        {
            for(i=1;i<=n; i++) /* cycle through 1 to n */
            {
    	    s = sqrt(i); /* obtain the square root */	
    
                if (fmod(s,2) == 0) /* use floating point modular because sqrt returns a float */
    				/* if the remainder of a division by 2 is 0, then the number is even */
    
    		printf("%d\n", (int)i); /* print i value resulting in even square roots */
               
            }  
        } 
        else
        {
            printf("Sorry, try inputting a positive number next time.\n");
        }
    
    return 0;
    }

    Compile your code as C, not C++.

If they do, I ask them to find the smallest example that exhibits the problem and send me that. Mostly, they then find the error themselves. "Finding the smallest program that demonstrates the error" is a powerful debugging tool.
