How to print a string variable to the brain screen

Hello, I am working on a project currently and have hit a roadblock. I have a string variable called text that acts as a parameter to a function, and within that function I want to print text to the brain screen. But, when I try “Brain.Screen.print(text)”, it throws this error

“C:\Program Files (x86)\VEX Robotics\VEXcode Pro V5\sdk/vexv5/include/vex_brain.h:198:28: error: cannot convert ‘std::basic_string’ to ‘int’ without a conversion operator
print( “%d”, (int)value );
^~~~~~~~~~
src/main.cpp:172:18: note: in instantiation of function template specialization ‘vex::brain::lcd::print<std::basic_string >’ requested here
Brain.Screen.print(text);
^
1 error generated.
make: *** [vex/mkrules.mk:13: build/src/main.o] Error 1
[error]: make process closed with exit code : 2”

Does anyone know how to fix this or get around this?

I just had this issue and here’s my search result:
“
You can fix it by converting it to a C-style string (const char*):

Brain.Screen.print(motorName.c_str());

“

Most of the time we face problems that someone, somewhere in the world had it before we did, so searching could be the quickest way to solving problems.
