Local variables are declared inside the function. Local variables must be declared before they have used in the program. Functions that are declared inside the function can change the value of variables. Functions outside cannot change the value of local variables. Here is an example int main()...

C provides several different types of numeric variables. You need different types of variables because different numeric values have varying memory storage requirements and differ in the ease with which certain mathematical operations can be performed on them. Small integers (for example, 1, 199, and...

Types and Variables There are several types in C++. They can be divided into two groups: simple and compounded. The simple types can be further classified into integral, floating, and logical types. The compunded types are arrays, pointers, and references. They are all (directly or indirectly...
