"Run-Time Check Failure #3 - The variable 'sum' is being used without being initialized."
我该如何修复这个错误？
#include <math.h>
#include <stdio.h>
int perfect_in_pow(int num) {
int nn = 0; // THE NUMBER OF THE DIGITS IN THE NUMBER
int temp; // USED TO SEPERATE A DIGIT FROM THE ENTIRE NUMBER
int temp2; // USED TO CALCULATE TO NUMBER OF TIMES THAT WE NEED TO ADD 1 TO "nn"
int temp3; // USED TO SAVE THE ORIGINAL ENTERED NUMBER'S VALUE
int power; // USED TO CALCULATE EACH DIGIT TO THE POWER OF "nn"
int sum; // THE SUMMERY OF THE "power" CALCULATION FOR EACH DIGIT
int ii; // USED IN THE FOR LOOP
temp2 = num;
temp3 = num;
do { // USED TO CALCULATE THE NUMBER OF THE DIGITS IN THE NUMBER
nn += 1;
temp2 = temp2 / 10;
} while (temp2 > 0);
while (num>0) { // USED TO CALCULATE THE SUMMERY
for (ii = 0; ii<nn; ii++) {
temp = num % 10;
power = pow(temp, nn);
sum += power;
num = num / 10;
}
}
if (temp3 == sum) {
return 1;
}
else {
return 0;
}
}
void main() {
int num;
printf("Enter a number ");
scanf("%d", &num);
printf("%d", perfect_in_pow(num));
}
我们将不胜感激。谢谢。
