c sizeof array length code example
Example 1: size of an array c
int a[20];
int length;
length = sizeof(a) / sizeof(int);Example 2: size of an array c
int a[]= { 1, 2, 3, 4, 5, 6, 7 };
int length = sizeof(a) / sizeof(a[0]); //return 7int a[20];
int length;
length = sizeof(a) / sizeof(int);int a[]= { 1, 2, 3, 4, 5, 6, 7 };
int length = sizeof(a) / sizeof(a[0]); //return 7
