3.3. 主函数调用各个模块

用switch语句判断输入者要使用的功能，然后调用函数，模块实现功能。程序如下：

void main() {

int j;char a;char x; char grade;

char searchkind[20]; char searchname[20]; i--;

system(\ do {

printf(\ printf(\手机通讯录 \\n\ printf(\功能选择 \\n\输出主界面 printf(\ printf(\查看 *\\n\ printf(\增添 *\\n\

. . .

printf(\删除 *\\n\ printf(\查询 *\\n\ printf(\修改 *\\n\ printf(\保存 *\\n\

printf(\

printf(\请选择(Choice)\\n\\n\\t\\t注:输入a~h或A~H的字母:\

scanf(\

switch(grade) //用switch判断使用者要选择的功能 {

case 'a':

case 'A': j=0; while(getchar()!=0x1b&&j<=i) {

Show(j++);

printf(\请按回车键继续!\ }

while(getchar()==0x1b||j>i) {

printf(\空文档,无任何记录-Empty Note\\n\ printf(\请按回车键继续!\ getchar(); break; }

printf(\此次操作结束\

printf(\----\\t\\t\\n\

break; case 'b':

case 'B':

while(i<=50) {

i++;

Append(i);

printf(\是否继续增加?(y/n)\ a=getchar(); if(a=='n')

break; }

if(i==51)

printf(\文档已满,无法增加记录-note full\ printf(\此次操作结束\

. . .

printf(\----\\t\\t\\n\

getchar(); break; case 'c':

case 'C': Delete(); if(i<1)

printf(\没有记录-No records\\n\ printf(\请按回车键继续!\ getchar();

getchar();

printf(\此次操作结束\

printf(\----\\t\\t\\n\

break; case 'd':

case 'D': system(\

printf(\请输入要查询记录的相关类别: p.个人类 b.商务类 w.办公类\

scanf(\ for(j=0;j<=i;j++) {

if(strcmp(searchkind,friends[j].kind)==0) {

Show(j); } }getchar();

break; case 'e':

case 'E':

printf(\请输入要修改记录的相关:\ gets(searchname);

scanf(\ for(j=0;j<=i;j++) {

if(strcmp(searchname,friends[j].name)==0) {

Modify(j); } }
