In C ++, an error occurs when the parameter names and variable names in the same class are the same. There are two solutions:

Class {
Int P;
Void fun (INT p ){
P = P;
}
}

For example, in the preceding example, If you obtain the value of the integer Variable P of A Class Object in the future, the system will re-simulate a default value, such as-838232304.

There are two solutions: One is through the this pointer

Class {
Int P;
Void fun (INT p ){
This-> P = P;
}
}

 

2. Change the parameter name

 

Class {
Int P;
Void fun (INT P1 ){
P = p1;
}
}

 

 

This problem is generally not a problem in advanced languages, but in C and C ++, try to develop the habit of not having the same parameter name as the variable name.
