I have declared an array in main() and to find the size of an array I can use sizeof() and this gives me the correct result. When the same array is passed to another user defined function and if I use sizeof() then I am not getting expected results. In the code I have attached, I get size of array as 10 in main() but in user defined function, I am getting array size as 2. My question is why its not showing 10? Or is there any other solution for this?
#include <stdio.h>
int array(int a[])
{
int x=sizeof(a)/sizeof(int);
printf("\n in user defined() size is %d",x);
}
int main()
{ int a[10],i,x;
for(i=0;i<4;i++)
a[i]=i+1;
x=sizeof(a)/sizeof(int);
printf("\n in main() size is %d",x);
array(a);
return 0;
}
output:
in main() size is 10
in user defined() size is 2
