    conversion errors

    Code:
    #include <stdio.h>
    
    int average(int a, int b, int c, int d, int e);
    
    int main (void)
    
    {
    	int a;
    	int b;
    	int c;
    	int d;
    	int e;
    	float f;
    
    	printf("Enter five numbers\n");
    	scanf ("%d", &a, &b, &c, &d, &e);
    
    	f = average(a,b,c,d,e);
    
    	printf("The average of the numbers you entered is %.2f\n",f);
    
    	return f;
    }
    
    int average(int a, int b, int c, int d, int e)
    
    {
    	return (int) (a+b+c+d+e)/5;
    
    }
    Why am I receiving conversion errors with this code?

    Average returns an int, but you put it in a float, then you try to return a float from main, which is defined to return int.

    >>scanf ("%d", &a, &b, &c, &d, &e);
    Not enough formats here, try
    >>scanf ("%d %d %d %d %d", &a, &b, &c, &d, &e);

    The return type of the average function is also wrong. Your confusing int's and float's.
    When all else fails, read the instructions.
    If you're posting code, use code tags: [code] /* insert code here */ [/code]
