However function system has declaration int system(const char *s); that is it accepts an argumnet of type const char * There is no conversion operator that would convert implicitly an object of type std::string to object of type const char *. Nevertheless class std::string has two functions that do this conversion explicitly. They are c_str() and data() (the last can be used only with compiler that supports C++11) So you can write string name = "john"; system( (" quickscan.exe resolution 300 selectscanner jpg showui showprogress filename '"+name+".jpg'").c_str() ); There is no need to use an intermediate variable for the expression. share|improve this answer edited Feb 5 '14 at 23:20 Remy Lebeau 231k13141269 answered Feb 5 '14 at 22:09 Vlad from Moscow 1 add a comment| up vote 6 down vote std::string + const char* results in another std::string. system does not take a std::string, and you cannot concatenate char*'s with the + operator. If you want to use the code this way you will need: std::string name = "john"; std::string tmp = "quickscan.exe resolution 300 selectscanner jpg showui showprogress filename '" + name + ".jpg'"; system(tmp.c_str()); See std::string operator+(const char*) share|improve this answer edited Feb 5 '14 at 22:08 answered Feb 5 '14 at 21:56 Ed S. 86.5k13131199 add a comment| up vote 2 down vote As all the o

new to C++ programming, for practice i'm building a basic currency converter, i'm receiving the error "cannot convert `std::string' to `const char*' for argument `1' to `int std::strcmp(const char*, const char*)'" when trying to compare the answer from the user with "Yes", "YES" or "yes".
