Question about function loop in C-language quiz games

You may have written a quiz game when you are new to C. However, when writing a guessing function, you cannot avoid using loops.

When a function is nested in a loop, your score variable may be reset to the initial value in the function body. So how can this problem be solved?

In fact, it is very simple. You need to add an accumulation variable to the loop body so that the single-cycle scoring of the function body becomes the final total point through the cycle in the main function, then, you can determine your final points and wins or losses.

Below are some of the code I have written. please correct me!

1. Function body

Int compare (int x, int y) {int j = 0; // each cycle outside the function initializes the value of j if (x <3 & x> 0) {if (y-x = 0) {printf! ");} If (y-x = 1 | x-y = 1) {if (x> y) {printf (" You won this quiz! Add one point! "); J ++;} else {printf (" The computer won this time! Minus one point! "); J -- ;}} if (y-x = 2 | x-y = 2) {if (x> y) {printf ("The computer won this quiz! Minus one point! "); J --;} else {printf (" You won this quiz! Add one point! "); J ++ ;}}} else {printf (" You entered an error! \ N ") ;}return j; // the return value is initialized in each main function loop}

2. main Subject

For (I = 0; I <5; I ++) {printf ("\ n"); printf ("Please input your fist! "); Scanf (" % d ", & x); y = rand () % 3; printf (" % d \ n ", y ); ary [I] = compare (x, y); sum + = ary [I]; // The initialization of score variables is easily solved using the sum variable}
