Question

当我使用3个或更多名字时，我的程序会输出奇怪的字符。

当我使用2完全没问题的时候，当我使用很多空格时也很好。

但是当我尝试的时候 kaue rodrigo pacheco 输出是： KRP]甲

#include <stdio.h>
#include <cs50.h>
#include <string.h>

int main(void)
{
string name = get_string("What is your name?\n");

// initiate array that will contain all the initials
char initials[10];

// initials index
int index = 0;

// if first character is not a space then append to initials
if (name[0] != 32)
{
        // if the character is not between A-Z
        if (!(name[0] >= 'A' && name[0] <= 'Z'))
        {
            // transform it in uppercase
            name[0] = name[0] - 32;
        }
        // append the character into initials array
        initials[index] = name[0];
        // keep track on how many were done
        index++;
}


// iterate through the user input
for (int i = 1; i < strlen(name); i++) 
{
    if ((name[i] != 32) && (name[i - 1] == 32))
    {
        // if the character after the blankspace is not between A-Z
        if (!(name[i] >= 'A' && name[i] <= 'Z'))
        {
            // transform it in uppercase
            name[i] = name[i] - 32;
        }
        // append the character into initials array
        initials[index] = name[i];
        // keep track on how many were done
        index++;
    }
}
// end result, prints all initials uppercase
printf("%s\n", initials);

}

添加

在initials[index] = 0;之前

printf。您不会使用零终止char数组。 C字符串中有多个字符，末尾为零

为什么我的程序输出奇怪的特征？
