How do you check if a string is not equal to another string in C++?
Two strings are said to be equal if they have same value at character level. Using C++, we can check if two strings are equal. To check if two strings are equal, you can use Equal To == comparison operator, or compare() function of string class.
Does != Work with string?
The != operator works for primitive types like int, char, boolean, and works for the first 128 String values if I recall right (*).
How do I check if a string is equal in C++?

> | Greater than | x > y |
< | Less than | x < y |
Can C++ characters be compared?
How can we compare two strings using operator overloading in C++?
C++ Program That Defines a Class String and Overload == Operator to Compare Two Strings [Operator Overloading Concept]
- #include //used. for gets() #include //used for strcmp()
- { char str[20]; public:
- gets(str); } //operator.
- } }; main()
- cout<<“Enter second string:”; s2.getdata(); if(s1==s2) //here.
