Your initialisation error is because you're assigning 'largest' the value of num1, and num1, at that point, hasn't been given a value (is not initialised). To fix the error you could assign num1 a value before using it, but what you really want to do (for this example) is set largest to zero.

Also, where you track which of num1, 2 or 3 is the largest, you need to set largest = num1/2/3, not num1/2/3 = largest, and your format specifier in the final printf needs to be %d (outputs an int), not %c (outputs a character).
