C Language: strcmp function (String Compare) In the C Programming Language, the strcmp function returns a negative, zero, or positive integer depending on whether the object pointed to by s1 is less than, equal to, or greater than the object pointed to by s2. The syntax for the strcmp function in the C Language is. Mar 17, 2018 Case-insensitive string comparison in using C11 lambda function and equals Logic is same as above, use std::equals but instead of another global function use lambda function and make solution in single line i.e. This string is compared to a comparing string, which is determined by the other arguments passed to the function. Parameters str Another string object, used entirely (or partially) as the comparing string. Pos Position of the first character in the compared string. If this is greater than the string length, it throws outofrange.
To compare two string in C Programming, you have to ask to the user to enter the two string and start comparing using the function strcmp. If it will return 0, then both string will be equal and if it will not return 0, then both string will not be equal to each other as shown in here in the following program.
C provides following two types of string representations − The C-style character string. The string class type introduced with Standard C. The C-Style Character String. The C-style character string originated within the C language and continues to be supported within C.
Hello! :)
I'm having a problem while comparing one character from a string with a ... string.
This is a part of a pretty complex loop (or, it's complex for me, since I'm new to C++ and programming), but the case is that I need to compare the value of a given i index of a string to a string. For example:
Well, this is just a silly example program, but I hope you see whats wrong (because I don't...)
Thanks! :)

Very simple mistake: if (str[x] 'a') should be: if (str[x] 'a') You are comparing each character from a string with another character, so you need single quotes instead of double

Actually, you are one of the few people who get the Code-tags right in their first post, so : bravo!

This came up in another thread. I gave some advice that I'm not longer sure of. Rather than hijacking that thread, I figured I'd start my own. I advised against using the in that thread. The context was this:
Ancient Dragon said the above was fine and that compare was unnecessary. So I wondered if maybe was only bad when comparing two string variables, so I did a little test program and it worked:
The line displayed to the screen. So my question is when is it bad to use when comparing strings? I thought the program above was not supposed to work. Apparently I was mistaken. If it's always fine to use , do we ever need to use the 'compare' function?

>>string subChoice ='; It isn't necessary to provide an initializer for strings because that's the default. Just string subChoice; is sufficient.
How To Compare Strings In C
>> do we ever need to use the 'compare' function You use it when you need to know if one string is less than, equal to, or greater than the second string, such as in sorting algorithms. You could also use the < and > operators but then that might be too slow when used in if conditions because the comparison would have to be repeated.
