Case-insensitive string comparison in C++ [closed]

Answer 1

Just use strcmp() for case sensitive and strcmpi() or stricmp() for case insensitive comparison. Which are both in the header file

format:

int strcmp(const char*,const char*);    //for case sensitive
int strcmpi(const char*,const char*);   //for case insensitive

Usage:

string a="apple",b="ApPlE",c="ball";
if(strcmpi(a.c_str(),b.c_str())==0)      //(if it is a match it will return 0)
    cout<

Output

apple and ApPlE are the same

a comes before b, so apple comes before ball
