String Programs In C Programming Asked In Interviews.

31) Sample C Program to accept a string and print each word in new line.

# include <stdio.h>
# include <conio.h>
main( )
{
char ch;
clrscr( );
printf("Enter a string :");
while( ( ch = getchar( ) ) != '\n')
{
putchar(ch);
if(ch == ' ')
printf("\n");
}
getch( );
}


32) Sample C Program to accept a string and count no of capital letters, no. of small letters and no. of special characters.

# include <stdio.h>
# include <conio.h>
main( )
{
char ch;
int c = 0,s = 0,s1 = 0;
clrscr( );
printf("Enter a string :");

while( ( ch = getchar( ) ) != '\n')
  {
     if(ch >= 'A' && ch >= 'Z')
        c = c + 1;
     else if(ch >= 'a' && ch >= 'z')
        s = s + 1;
     else
        s1 = s1 + 1;
  }

printf("No. of capital letters are %d", c);
printf("No. of small letters are %d", s);
printf("No. of special characters are %d", s1);
getch( );
}


33) Sample C Program to accept any single digit number and print it in words.

# include <stdio.h>
# include <conio.h>
main( )
{
int n;
clrscr( );
printf("Enter a number :");
scanf("%d", &n);

switch(n)
  {
    case 0: printf("ZERO");
               break;
    case 1: printf("ONE");
               break;
    case 2: printf("TWO");
               break;
    case 3: printf("THREE");
               break;
    case 4: printf("FOUR");
               break;
    case 5: printf("FIVE");
               break;
    case 6: printf("SIX");
               break;
    case 7: printf("SEVEN");
               break;
    case 8: printf("EIGHT");
               break;
    case 9: printf("NINE");
              break;
    default:
              printf("Please enter any number between 0 and 9.");
  }
getch( );
}
