atoi似乎不能正常工作

Question

for(int y = 0; y < 5; y++)
{   
   char cst1[2] = {info[x+2], info[x+3]};
   char cst2[2] = {info[x+5], info[x+6]};
   sales[count][atoi(&info[x]) - 1] = atoi(cst1) + atoi(cst2);
   x += 8;
}

每次我执行以下代码时，atoi(cst1)值乘以2，然后相加，atoi(cst2)乘以100，然后相加，我不知道为什么

Answer 1

cst1和cst2似乎不是以NUL结尾的。

char cst1[] = {info[x+2], info[x+3], '\0'};
char cst2[] = {info[x+5], info[x+6], '\0'};
