Problem statement:-  Program to Check whether two strings are the same or not

 Data requirement:-

   Input Data:- str, str2

  Output Data:- Nothing

  Additional Data:-i, count

Program in C

Here is the source code of the C Program to Check whether two strings are the same or not.

Code:

#include<stdio.h>
#include<string.h>
int main()
{
    char str[30];
    printf("Enter your 1st String:");
    gets(str);
    char str2[30];
    printf("Enter your 2nd String:");
    gets(str2);
    if(strlen(str)!=strlen(str2))
    printf("Strings characters are not same.");
    else
    {
    int i,count=0;

    for(i=0;i<strlen(str);i++)
    {

        if(str[i]==str2[i]){
            count=1;
            break;
    }}
    if(count!=1)
    {
        printf("Strings characters are not same.");
    }
    else
        printf("Strings characters are the same.");
}}

Input/Output:

Enter your 1st String:csinfo
Enter your 2nd String:csinfo
Strings characters are the same.

Program in C++

Here is the source code of the C++ Program to Check whether two strings are the same or not.

Code:

#include<iostream>
using namespace std;
int main()
{
    string str,str2;
    cout<<"Enter your 1st String:";
    getline(cin,str);

    cout<<"Enter your 2nd String:";
    getline(cin,str2);

    int len=0,len2=0,i;
    while(str[len]!='\0')
    {
        len++;
    }

    while(str2[len2]!='\0')
    {
        len2++;
    }

    if(len!=len2)
    cout<<"Strings character are not the same.";
    else
    {
    int i,count=0;

    for(i=0;i<len;i++)
    {

        if(str[i]==str2[i]){
            count=1;
            break;
    }}
    if(count!=1)
    {
        cout<<"Strings character are not the same.";
    }
    else
        cout<<"Strings character are the same.";
}}

Input/Output:

Enter your 1st String:csinfo
Enter your 2nd String:dotcom
Strings characters are not the same.

Program in Java

Here is the source code of the Java Program to Check whether two strings are the same or not.

Code:

import java.util.Scanner;
public class P31 {

public static void main(String[] args) {
Scanner cs=new Scanner(System.in);
String str1;
System.out.println("Enter your 1st String:");
str1=cs.nextLine();
String str2;
System.out.println("Enter your 2nd String:");
str2=cs.nextLine();
if(str1.length()!=str2.length())
System.out.println("Strings are not the same.");
    else
    {
    int i,count=0;
    char[] str_1=str1.toLowerCase().toCharArray();
    char[] str_2=str2.toLowerCase().toCharArray();
    
    for(i=0;i<str1.length();i++)
    {

        if(str_1[i]==str_2[i]){
            count=1;
            break;
    }}
    if(count!=1)
        System.out.println("Input strings are not the same.");
    else
    System.out.println("Input strings are the same.");
}
cs.close();
}
}

Input/Output:

Enter your 1st String:
cat
Enter your 2nd String:
tac
Input strings are not the same.

Program in Python

Here is the source code of the Python Program to Check whether two strings are the same or not.

Code:

str=input("Enter the 1st String:")
str2=input("Enter the 2nd String:")
count = 0
if len(str) != len(str2):
    print("Strings are not the same.")
else:
    for i in range(0,len(str)):
        if str[i] == str2[i]:
            count=1
            break
    if count!=1:
        print("Input strings are not the same.")
    else:
        print("Input strings are the same.")

Input/Output:

Enter the 1st String:info
Enter the 2nd String:info
Input strings are the same.
