hi
i will give u a simple example of scope of local and staic variable
#include<stdio.h>
void print_value(void)
main()
{
int i;
for(i=0;i<=5;i++)
{
printf("iteration no:%d",i);
printf_value();
}
return 0;
}
void print_value(void)
{
static int x=0;
int y=0;
printf("values: x=%d ,y=%d\n",x++,y++);
}
if u run this program output is:
iteration no:0 values :x=0,y=0
iteration no:1 values :x=1,y=0
iteration no:2 values :x=2,y=0
iteration no:3 values :x=3,y=0
iteration no:4 values :x=4,y=0
iteration no:5 values :x=5,y=0
1. difference is that local variable is created and destroyed each time when
function is called.
but static variable retain the same value when that function is called.
here y is always initialized to 0 when print_value is called but static
have same old value.
2.local variable is initialized every time but static variable is
initialized once need not reinitialized
