printf("\nEnter an integer value : ");
scanf("%d", &i);

printf("\nEnter a floating point value : ");
scanf( "%f", &f );

printf("\nEnter a character value : ");
fflush(stdin);
scanf("%c", &ch);

/* Display variable values */
printf("\nInteger = %d\nFloat = %f\nCharacter = %c", i, f, ch);

return 0;
