Question

I compiled this code on my WxDev C++. By theory it should output the users’ answer and the correct answer. It did, with an exception of array number 0 of the coranswers array, showing just a blank space. I tried compiling it on other PCs and the problem wasn’t present. I tried reinstalling the WxDev, even as far as replacing it with codeblocks. Seems like the problem is on my PC. What should I do?

#include<stdio.h>
int main(){
char coranswers[20] = {'A', 'B', 'C', 'D', 'E', 'A', 'A', 'A', 'A', 'A', 'A', 'A', 'A', 'A', 'A', 'A', 'A', 'A', 'A', 'A'};
char answers[20];
int count;
int grade = 0;

for(count = 0; count < 20; count++){
          printf("No.%d ", count+1);
          scanf("%s", &answers[count]);
          }
for(count = 0; count < 20; count++){
          printf("No.%d ", count+1);
          printf("Your answers : %c\n", answers[count]);
          if(answers[count] == coranswers[count]){
                            grade++;
                            }
          else{
               printf("Wrong answer, correct answer is %c\n", coranswers[count]);
          }
          }
          return 0;
          }

You don’t want to read a string into a char array

scanf("%s", &answers[count]); // the format string should be "%c"
