String as datatype In C, we know string basically a character array terminated by\0. Thus to operate with the string we define character array. But in C++, the standard library gives us the facility to use the string as a basic data type like an integer. Like integer comparisons, we ca...
The converted operands of equality operators == and != can also have the type std::nullptr_t,(since C++11) pointer type or pointer-to-member type. Built-in pointer equality comparison has three possible results: equal, unequal and unspecified. The values yielded by equality operators for ...
Pointer comparison operatorsFor every type P which is either pointer to object or pointer to function or std::nullptr_t (until C++14), the following function signatures participate in overload resolution: bool operator<(P, P); bool operator>(P, P); bool operator<=(P, P); bool ...
Hi! There are some strange issues while using spaceship operators with latest VS versions. For example I have struct in my project: struct BlendState { bool independ_blend = false; std::array<RenderTarget, 8> render_target; bool operator==(const BlendState&) const...
Comparison Between Signed and Unsigned Integer Expressions in C++ C++ supports signed and unsigned integers, which are written asintandunsigned int. When using signed integers, you can use the relational operators to compare two values. The relational operators will not work because they always evaluat...
Output -1 0 Explanation At first, since 'a' (ASCII 97) is less than 'b' (ASCII 98) so output is a negative number (-1). In the second, the output is 0 as values stored in str1 and "apple" are the same. Print Page

When the strings or variables contain spaces or special characters, put them in double quotes. With the if command, you can use /I for a case insensitive string comparison and NOT to run the command if the condition is false. You can also use comparison operators such as EQU (equal), NE...
