sizeof

#include #include int main(){ int i; i = 10; printf("i : %d\n",i); printf("sizeof(i++) is: %d\n",sizeof(++i)); printf("i : %d\n",i); return 0;} Result: I: 10 Sizeof (I ++) is: 4I: 10 Sizeof is an operator, but does not calculate

Today, when programming, simply use the following procedure to find the number of elements in a vector container:vectorint> vec; for (int0; i++) { vec.push_back (i);} int sizeof sizeof (int);The program runs as a result of size=4 (sizeof (VEC) =1
