Thread: A little Help with a small program

Here is the code...

Code:

#include <stdio.h>

int main()
 {
 int x,y;
 char choice;
  printf("\n  Number Squarer/SquareRooter; Coded by whtpirate(elder(justin)) of LogiTeam.\n");
  puts("\n");
  
  // Start of the main stuff.
  printf("\tWhat do you want to do? (s/sr): ");
  scanf("%c", &choice);
  if (choice == 's')
   { 
    printf("\n\tEnter any number: ");
     scanf("%d", &x);
     // This is what squares the numbers
       y = x*x;
         printf("\n\t'%d' is your number squared.\n", y);
    }
  if (choice == 'sr')
    {
     printf("\tEnter any number: ");
      scanf("%d", &x);
       // This is what squareroots the numbers
       y = x^x;
        printf("\n\t'%d' is your numbers sq-rooted.\n", y);
     }         
 return 0;
}

>>if (choice == 'sr')

Choice is a char. Thus, it holds one character. You will need to use a character array and strcmp to check multiple letters.

Hey guys I got it working thanks to your help and a friend of mines helps

Code:

#include <stdio.h>

int main()
 {
int x;
float y;
char choice[3];
 
  printf("\n  Number Squarer/SquareRooter; Coded by whtpirate(elder(justin)) of LogiTeam.\n");
  puts("\n");
  
  // Start of the main stuff.
  printf("\tWhat do you want to do? (s/sr): ");
   scanf("%2s", choice);
  if (!strcmp(choice, "s"))
   { 
    printf("\n\tEnter any number: ");
     scanf("%d", &x);
     // This is what squares the numbers
       x *=x;
         printf("\n\t'%d' is your number squared.\n", x);
    }
  if (!strcmp(choice, "sr"))
    {
     printf("\tEnter any number: ");
      scanf("%d", &x);
       // This is what squareroots the numbers
       y = sqrt(x);
        printf("\n\t'%.0f' is your number sq-rooted.\n", y);
     }         
 return 0;
}
