can you guys fix it for me

it is C++ coding I have an error and I am confuse

Solution

Everything is fine except the following :

- you have used the return type int for \"processTargetHeartRate\" function which you have not received in main function.

- you have mentioned int parameter for \" processTargetHeartRate\" function but you hadn\'t sent an parameter while calling it from main function

- in calculateMaximumHeartRate function return statement may or may not have expression , please check it out
