C语言学习笔记之字符串拼接的2种方法

1. 使用strcat进行字符串拼接 #include <stdio.h> #include <stdlib.h> #include <string.h> int main() { char *firstName = "Theo"; char *lastName = "Tsao"; char *name = (char *) malloc(strlen(firstName) + strlen(lastName)); strcpy(name, firstName); strcat(name, lastName); printf("%s\\n", name); return 0; } 2. 使用sprintf进行字符串拼接 #include <stdio.h> #include <stdlib.h> #include <string.h> int main() { char *firstName = "Theo"; char *lastName = "Tsao"; char *name = (char *) malloc(strlen(firstName) + strlen(lastName)); sprintf(name, "%s%s", firstName, lastName); printf("%s\\n", name); return 0; }
