Local and Global Variables in C

Local Variables : Variables declared inside the body of a function or the main program, these variables are called Local Variables.
Example :

void main()
{
 int x, y, i,j;  // local variables in main()
float a[3][3];
 ----------
  ----------
 ----------
}
int test(float b[][], int x, int y)
{
 int i, j, k;      // local variables in function
  ----------
  ----------
 ----------
}

Global Variables : Variables are declared outside the body of the main program, these type variables are called Global Variables.

int x, y, i,j;   // Global variables
void main()
{
   
float a[3][3];
 ----------
 ----------
 ----------
}
int test(float b[][])
{
 int k;
