Naming the variable is important

We must take special care while naming the variable else it will lead to mystification.

Let us consider the following two code snippets

Code 1:

int main()

{

int i=3,j=5,k=0;

k = i*j;

printf(“area of rectangle = %d”,k);

return 0;

}

Code 2:

int main()

{

int base=3,height=5, rect_area=0;

rect_area = base*height;

printf(“area of rectangle = %d”,rect_area);

return 0;

}

 

The above two programs used to find the area of rectangle. However which one of it gives more meaning?

Do the variables (i,j,k) in Code 1 give any sort of meaning? They lead to confusion, don’t they?

Where as the variables (base, height, rect_area) in Code 2 give us more meaning than the Code 1.

So always try to give meaningful names to the variable.
