c语言 把多个单词连成一个字符串,中间用空格隔开

Answer 1

举个简单例子，不给完整代码了。
char* str1 = "I am No.1";
char* str2 = "I am No.2";
char* str3 = "I am No.3";
int totalLen = strlen(str1) + 1 + strlen(str2) + 1 + strlen(str1) + 1 ;
char* strAll = (char*) malloc(totalLen * sizeof(char));
strcpy(strAll, str1);
strcat(strAll, " ");
strcat(strAll, str2);
strcat(strAll, " ");
strcat(strAll, str3);
...
...
...
free(strAll);
