C Global Scope
- The variables declared right before the main function is called as global variables.
- Global variables can be accessed through out the program.
C program - Global Scope
globalscope.c
#include <stdio.h>
int m1 = 5, m2 = 10;//global variable declaration
void add();
int main()
{
int mul;
mul = m1 * m2;
printf("\nMultiplication of %d and %d : %d ", m1, m2, mul);
add();
return 0;
}
void add()
{
int sum;
sum = m1 + m2;
printf("\nSum of %d and %d : %d ", m1, m2, sum);
}
- Multiplication of 5 and 10 : 50
- Sum of 5 and 10 : 15
Note:
The variables m1 and m2 are declared outside all functions. So, those can be accessed in any function within a program.
