Write a C program to print the message in reverse order using for loop in strings

Here we write a program to reverse the sentence without predefined functions. By using for loop, we can easily print statement in reverse order.

Program 1

#include<stdio.h>
int main(){
   char stmt[100];
   int i;
   printf("enter the message:
");
   for(i=0;i<stmt;i++){
      stmt[i]=getchar(); //reading each char from console till enter or newline char is pressend
      if(stmt[i]=='
')
         break;
   }
   printf("the reverse statement is:
");
   for(i--;i>=0;i--) //printing each char in reverse order
   putchar(stmt[i]);
   putchar('
');
   return 0;
}

Output

enter the message:
Hi welcome to my world
the reverse statement is:
dlrow ym ot emoclew iH

Program 2

Here, we will write a C program to reverse a string using strrev library function −

#include<stdio.h>
#include<string.h>
void main(){
   //Declaring two strings//
   char result[50],string[25];
   //Reading string 1 and String 2//
   printf("Enter String to be reversed : ");
   gets(string);
   //Reversing using library function//
   strrev(string);
   printf("The reversed string is : ");
   puts(string);
}

Output

Enter String to be reversed : Hi welcome to tutorials Point
The reversed string is : tnioP slairotut ot emoclew iH
