#include <stdio.h>
#include<stdlib.h>
#include <string.h>
int main(){
char *ch;
ch=(char*)calloc(30,sizeof(char));
strcpy(ch,"iloveyouchina");
printf("%s\n",ch);
free(ch);
return 0;
}
利用calloc()函数申请内存，将iloveyouchina写入
#include <stdio.h>
#include<stdlib.h>
#include <string.h>
int main(){
char *ch;
ch=(char*)calloc(30,sizeof(char));
strcpy(ch,"iloveyouchina");
printf("%s\n",ch);
free(ch);
return 0;
}
