入一行字符分别统计出其中英文字母、数字、空格和其他字符的个数。输入一行字符输出统计值样例输入 aklsjflj123 sadf918u324 asdf91u32oasdf;123样例输出23 16 2 4用c语言写

#include <stdio.h>

int main() {
    char str[100];
    scanf("%[^\n]", str);
    
    int i = 0;
    int letterCount = 0;
    int digitCount = 0;
    int spaceCount = 0;
    int otherCount = 0;
    
    while (str[i] != '\0') {
        if ((str[i] >= 'a' && str[i] <= 'z') || (str[i] >= 'A' && str[i] <= 'Z')) {
            letterCount++;
        } else if (str[i] >= '0' && str[i] <= '9') {
            digitCount++;
        } else if (str[i] == ' ') {
            spaceCount++;
        } else {
            otherCount++;
        }
        i++;
    }
    
    printf("%d %d %d %d\n", letterCount, digitCount, spaceCount, otherCount);
    
    return 0;
