Indefinite loop in C Program

Program #16

Description:
To iterate indefinite loop until user press any keyboard characters.

void main(){
clrscr();
 /*
 Indefinite loop using kbhit() function
 kb  - KeyBoard
 hit - Type/Enter
 */
 for(;!kbhit();){
    printf(" * \t @ \t & \t %");
 }
 getch();
}

Note:
kbhit() functionality will not obey for few keyboard characters.. I am expecting the answer from blog readers.  Once you know the key.. Reply it.!!

Find a String is Palindrome or not in C Program

Program #15

Description:
To find a given string is PALINDROME or not

What is palindrome?

DUMMY != YMMUD
PALINDROME != EMORDNILAP

LIRIL   = LIRIL
AMMA = AMMA

If a string and its reversed string is same then that string is a "Palindrome".

#include<stdio.h>
void main(){
 char palind[50], compar[50];
 int i,j=0, IsPalind;

 clrscr();
 printf("Please Enter a String to find Palidrome or not?\n");
 scanf("%s", &palind);

 for(i=strlen(palind)-1; i>=0; i--){
   /* Assign last char of Input string into first position of Compare array */
   compar[j]=palind[i];
   j++;
 }

 /* Compare both array to find Palindrome or not */
 IsPalind = 1;
 for(i=0; i<strlen(palind); i++){
   if (palind[i] != compar[i] ){
      IsPalind = 0;
      /* If single character not match, go out of the Loop*/
      break;
   }
 }

 printf("\n\nResult:\n");
 printf("-------\n");

 if (IsPalind){
   printf("Input String is a Palindrome !!");
 } else {
   printf("Invalid Input, Better luck next time !!");
 }

 getch();
}

Text and Background color print in C Program

int main(void)
{
   int i;
   clrscr();
   for (i=0; i<15; i++)
   {
       /* Just positioning to center */
       gotoxy(30,i+1);
       cprintf("Let Us C");
       cprintf("\r\n");
   
    /* set text color */
       textcolor(i+1);

main() function and return datatype in c

Description:
Why we need to keep void always to main().
Shall we try assign different type of datatypes?

Program #8
/* Usual way of void as return to main() */
# include "stdio.h"
void main(){
  clrscr();
  printf("void main() function in c (no more return) !!");
  getch();
 
  //no return
}

Output:
void main() function in c (no more return) !!

Program #9
/* int as return datatype to main() */
# include "stdio.h"
int main(){
  clrscr();
  printf("main() function in c (return integer) !!");
  getch();
 
  //return integer value, any as you wish
  return 1306;
}

Output:
main() function in c (return integer) !!

Program #10
/* float as return datatype to main() */
# include "stdio.h"
float main(){
  clrscr();
  printf("main() function in c (return float) !!");
  getch();
 
  //return float value, any as you wish
  return 13.06;
}

Output:
main() function in c (return float) !!

Program #11
/* char as return datatype to main() */
# include "stdio.h"
char main(){
  clrscr();
  printf("main() function in c (return char) !!");
  getch();
 
  //return char value, any as you wish
  return 'm';
}

Output:
main() function in c (return char) !!

Program #12
/* double as return datatype to main() */
# include "stdio.h"
double main(){
  clrscr();
  printf("main() function in c (return double) !!");
  getch();
 
  //return double value, any as you wish
  return 130600;
}







Output:
main() function in c (return double) !!
