Question for c++ programmers?

i need to write a function that reads in an operator (+,-,*,/) and returns a boolean. true if the operator is valid and false if it is not. the function will have two parameters. one is a string containing the valid operators (+,-,*,/), the second is a reference parameter where the operator will be placed if the operator entered is valid.





how can i do this? i just can't figure out how to write the code.

Question for c++ programmers?
u need to use pointer and function using call by reference


passing those pointers


in function u wud just check the validity


ur funtion may look like


void checker(bool *validity, char * string_operator);
