ALLOCATE SPACE FOR A STRING DYNAMICALLY AND

PRINT  THE STRING BACKWARDS

Aim

To write a program in c to allocate space for a string dynamically and print the string backwards

Algorithm:

1.Start the program.
2.Declare the pointer variable s.
3.Allocate the memory space using malloc.
4.Ifs = = NULL, allocation is not done. Else done successfully.
5.Get the string from the user
6.Read the string from backward and print the result.
7.Stop the program.

Program

#include <stdlib.h>

#include <stdio.h>

#inciude <string.h>

mt main(void)

{

char *S;
register int i;

s = malloc(80);

if(!s) {
printf(”Memory request failed.\n”);
exit(1);

}

gets(s);
for(i = strien(s) - 1; i >= 0; i--) putchar(s[ i ]);

free(s);
return 0;
}

Output:
        Hai
        iaH

Result:
Thus the program is written and executed to allocate space for a string dynamically and print the string backwards.
