Hello, i need help to read the content of a string and get it to add it a value. The variable will already be declared.

string mystring;
int minValue;

myString = "minValue";

myString.unknowCommand() = 5;

Serial.print(minValue);

This will print me 5.

Someone know if the "unkowCommand" exist and what is it??

Sorry I forgot the "". I don't want to transfer the char 5 in integer. I want to put 5 to the variable that my string contain in text.

You can't. Variable names cease to exist after the source code is compiled.

Convert string to int. Do math. Convert result back to string.
