字符数组和字符指针应用举例

#include <stdio.h>#include <stdlib.h>void wtFile(char fileNam[]);void wtFile2(char *fileNam);int main(){char nam[16] = "daniel.txt";wtFile(nam);char nam2[16] = "lyc.txt";wtFile2(nam2);char *nam3 = "lyc_daniel.txt";wtFile(nam3);char *nam4 = "daniel_lyc.txt";wtFile2(nam4);char nam5[16] = "lycDaniel.txt";char *nam6 = nam5;wtFile2(nam6);char nam7[16] = "danielLyc.txt";char *nam8 = nam7;wtFile(nam8);system("pause");return 1;}void wtFile(char fileNam[]){FILE *fp = fopen(fileNam,"w");fprintf(fp,"%c",'a'); //输入一字符fclose(fp);}void wtFile2(char *fileNam){FILE *fp = fopen(fileNam,"w");fprintf(fp,"%c",'a'); //输入一字符fclose(fp);}
