I'm currently working on an assignment for my class. In C, I have to make a program that works with the roster of a soccer team, where you can update, replace, compare players etc. However, right now I cannot make any of the options in my menu work. This will probably be better understood with my code:

#include <stdio.h>

int main(void) 

 int i, jersey, rating, newJersey, newRating, playerJerseyNumber[5], playerRating[5];
 char choice;

 for (i = 0; i < 5; i++)
 
 printf("Enter player %d's jersey number: n", (i + 1));
 scanf("%d", &playerJerseyNumber[i]);
 printf("Enter player %d's rating: nn", (i + 1));
 scanf("%d", &playerRating[i]);
 

 printf("ROSTERn");
 for (i = 0; i < 5; i++)
 
 printf("Player %d -- Jersey number: %d, Rating: %dn", (i + 1), playerJerseyNumber[i], playerRating[i]);
 

 printf("nnMENU nu - Update player rating na - Output players above a rating nr - Replace player no - Output roster nq - Quitnn");
 printf("Choose an option: n");
 scanf("%c", &choice);

 switch (choice) 
 case 'u':
 
 printf("Enter a jersey number: n");
 scanf("%d", &jersey);
 printf("Enter a new rating for player: n");
 scanf("%d", &newRating);
 for (i = 0; i < 5; i++)
 
 if (jersey == playerJerseyNumber[i])
 
 playerRating[i] = newRating;
 
 
 break;
 

 case 'a':
 
 printf("Enter a rating: n");
 scanf("%d", &rating);
 printf("n ABOVE %dn", rating);
 for (i = 0; i < 5; i++)
 
 if (playerRating[i] > rating)
 
 printf("Player %d -- Jersey number: %d, Rating: %dn", (i + 1), playerJerseyNumber[i], playerRating[i]);
 
 
 break;
 

 case 'r':
 
 printf("Enter a jersey number: n");
 scanf("%d", &jersey);
 printf("Enter a new jersey number: n");
 scanf("%d", &newJersey);
 printf("Enter a rating for the new player: n");
 scanf("%d", &newRating);
 for (i = 0; i < 5; i++)
 
 if (jersey == playerJerseyNumber[i])
 
 playerJerseyNumber[i] = newJersey;
 playerRating[i] = newRating;
 
 
 break;
 

 case 'o':
 
 printf("ROSTERn");
 for (i = 0; i < 5; i++)
 
 printf("Player %d -- Jersey number: %d, Rating: %dn", (i + 1), playerJerseyNumber[i], playerRating[i]);
 
 break;
 

 default:
 printf("didnt work");
 break;
 

 return 0;

now, the first part of my code works correctly. however, if i try to use any of the options in the menu, they do not work. it automatically goes to the default case and prints "didn't work".

right now, i am testing with

84 7
23 4
4 5
30 2
66 9
u
4
6
o
q

which does not work, even though it should update jersey #4 to a rating of 6.

Any ideas on why this isn't working? thanks.

use scanf(" %c", &choice) 

The blank in the format string tells scanf to skip leading whitespace, and the first non-whitespace character will be read with the %c conversion specifier.
