After opening the file, use the fseek () function to move the file position pointer to the end of the file, using Ftell () to get the position pointer from the file header bytes, the number of bytes is the length of the file. However, this is also

1. Storage categories for Variables From the angle of the existence of variable value, it can be divided into static storage mode and dynamic storage mode. The so-called static storage means that the system allocates a fixed amount of storage space

Program:The sum of the first 5 items of sn = a + AA + AAA + AAAA + AAAAA, where A is a number, for example: 2 + 22 + 222 + 2222 + 22222#include int main (){int i = 0;int a = 0;int sum = 0;int num=0;scanf ("%d", &num);for (i = 0; i {A = a * ten + num;
