#include<stdio.h>
int main()
{
char str[]={'a','b','c'};
char str1[]={"abc"};
printf("%d",sizeof(str));
printf("%d",sizeof(str1));
getchar();
}
This is giving 3 in case of str and 4 in case of str1 bcz str is "array of
character" and str1 is a "string".
For understanding this point consider a integer array int arr[] =
{1,2,3,4}; then for this sizeof(arr) is 16 means 4*sizeof(int). So in the
same way for str in given program it is giving 3*sizeof(char) i.e. 3.
sizeof(anyString) = lengthOfString +1 ( +1 for '\0')
strlen(anyString) = simple length
sizeof(anyArray) = numberofElementPresentInArray*sizeof(dataType)
