1 Write a validation loop that prompts the user for a number

1.) Write a validation loop that prompts the user for a number between 100 and 200, inclusive. If the number is outside that range, print a message and prompt the user again.

2.) Write a sentinel loop that prompts the user for a character between ‘d’ and ‘s’, inclusive. Whether the character is inside or outside that range, print a message. Continue to prompt the user for a character until they enter ‘!’ (the sentinel value).

Solution

1)

#include <stdio.h>

int main(void)
{
   int number;
  
   do
   {
       printf(\"\ Enter the number in the range 100 and 200 inclusive\");
       scanf(\"%d\",&number);
       if(number >= 100 && number <= 200)
       break;
   }while(number <100 || number > 200);
   return 0;
}

output:

Success time: 0 memory: 2172 signal:0

2)

#include <stdio.h>

int main(void)
{
   char ch;
  
   do
   {
       printf(\"\ Enter a character between \'d\' and \'s\' inclusive\");
       scanf(\"%c\",&ch);
       if(ch >= \'d\' && ch <= \'s\')
       break;
   }while(ch <\'d\' || ch > \'s\');
   return 0;
}

output:

Success time: 0 memory: 2172 signal:0
