的atoi似乎沒有正常工作

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; 
} 

每次我做下面的代碼的atoi（CST1）值乘以二，然後添加的atoi（CST2）乘以100，再加入無法弄清楚，爲什麼

Answer 1

cst1和cst2似乎不是NUL終止。

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