strrev() Reversing a string

#include<stdio.h>
#include<string.h>

int main()
{
   char str[30] = "plus2net";
   printf("String after reverse  : %s",strrev(str));
   return 0;
}

strlen(strrev);

Example 2

#include<stdio.h>
#include<string.h>

int main()
{
   char str[30] = "plus2net";
   strcpy(str,strrev(str));
   printf("String after reverse  : %s",str);
   return 0;
}

Example Using one input string

#include<stdio.h>
#include<string.h>

int main()
{
 char str[30];
   printf("Enter a string   ");
	scanf("%s",str);
   strcpy(str,strrev(str));
   printf("String after reverse  : %s",str);
   return 0;
}

Printing in reverse order without using strrev()

#include<stdio.h>
#include<string.h>

int main()
{
 char str[30]="plus2net";
 int str_length;
 str_length=strlen(str); // length of the string
 for(int i=str_length; i>=0; i--){
 printf("%c",str[i]);   // printing the char at position  i
 }
return 0;
}

Example : Reversing Strings in an Array

This example shows how to reverse multiple strings stored in an array.

#include <stdio.h>
#include <string.h>

void reverse_string(char str[]) {
    int n = strlen(str);
    for (int i = 0; i < n / 2; i++) {
        char temp = str[i];
        str[i] = str[n - i - 1];
        str[n - i - 1] = temp;
    }
}

int main() {
    char str_arr[3][50] = {"plus2net", "hello", "world"};
    
    for (int i = 0; i < 3; i++) {
        reverse_string(str_arr[i]);
        printf("Reversed string %d: %s\n", i + 1, str_arr[i]);
    }
    
    return 0;
}
