Hello. I want the user to enter a string, and then i want to see if what he entered matches my criteria using if statement but i can't seem to get it working. how would you use an if statement on a string array, can you show me a small example?thanks
some code?
all i can think of with what you said is something like this:or:Code:... if(!strcmpi(somestring,anotherstring)){...} ...//edit: that's in the <cstring> libraryCode:... if(!strcmpi(somestring,"constant string")){...} ...

I might be wrong, but I thought that the boolean equals operator (==) was overloaded for the STL string class.

I think jrahhali (wtf @ name) must be using C-strings.
If that's the case, then jrahhali, look up the <string> STL

Code:if (strcmp(string,"Value")==0) { echo "TRUE"; }
echo? Shell script?
How 'bout: cout << "TRUE";

But you get the picture.
Here are some traditional C string functions:
Works great for crude validation/parsing too.Code:const char * findfirstof(const char * ctn, const char * cmp) { const char * base = cmp; for(; *ctn != 0; ++ctn) { for(cmp=base; *cmp != 0; ++cmp) if(*ctn == *cmp) return ctn; } return 0; } const char * findfirstnotof(const char * ctn, const char * cmp) { const char * base = cmp, vld; for(; *ctn != 0; ++ctn) { vld = ctn; for(cmp=base; *cmp != 0; ++cmp) if(*ctn == *cmp) vld = 0; if(vld) return vld; } return 0; }

Code:#include <cmath> #include <complex> bool euler_flip(bool value) { return std::pow ( std::complex<float>(std::exp(1.0)), std::complex<float>(0, 1) * std::complex<float>(std::atan(1.0) *(1 << (value + 2))) ).real() < 0; }
