Can we compare strings from user input?

Question

There are two string values entered
char a[5]=Yes;
char b[5] ;//which is a user input;
If b[5] is equal to yes then print true other wise print false.
Show it by programming a code.

Answer 1

C++:

#include <iostream>
#include <string>

int main()
{
std::string s1 = "Hello";
std::string s2;

std::cout << "Enter a string: ";
std::cin >> s2;

// Works because of operator overloading
// You can also use !s1.compare(s2)
if (s1 == s2)
std::cout << "Strings are equal!\n";
else
std::cout << "Strings are not equal!\n";

return 0;
}

C:

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

int main(void)
{
const char *s1 = "Hello";
char s2[32];

fputs("Enter a string: ", stdout);
scanf("%31s", s2);

if (!strcmp(s1, s2))
puts("Strings are equal.");
else
puts("Strings are not equal.");

return 0;
}

Python:

s1 = "Hello"

print("Enter a string:", end = ' ')
s2 = input()

if s1 == s2:
print("Strings are equal.")
else:
print("Strings are not equal.")

Answer 2

yes ,you can compare input strings and string literals in C with strcmp() and in C++ with == or compare() for std::string. In python you can compare two strings with ==.

Answer 3

Show me any code

Answer 4

Strings can not be compared using the == comparison operator so strcmp() should be used here.
