Question

请编写一个函数,用来删除字符串中的所有空格

Answer 1

很简单的程序，遍历输入字符串，如果字符不是空格，就赋值到输出字符串中，如果是空格，就跳过这个字符。 #include <stdio.h> #include <string.h> int main() { const char * input = "Hello World! Welcome To Beijing!"; char output[1024]; int i, j, input_len; input_len = strlen(input); j = 0; for(i = 0; i < input_len; i++) { if (input[i] != ' ') { output[j] = input[i]; j++; } } output[j] = '\0'; printf("Input string is: %s\n", input); printf("After spaces were removed: %s\n", output); return 0; } 具体的输出效果为： Input string is: Hello World! Welcome To Beijing! After spaces were removed: HelloWorld!WelcomeToBeijing!
