程序运行结果如下图所示：

================================= 实验七 字符处理

=================================

1.---------------------------------------------------

该程序的功能是：输入字符串，删除其中的数字，保留剩下的字符。 #include main() { char a[40],b[40]; int i,j; printf(\ scanf(\ i=j=0; while (a[i]!='\\0') { if (! (a[i]>='0'&&a[i]<='9') ) { b[j]=a[i]; j++; } ++i; } b[j]='\\0'; printf (\}

5.--------------------------------------------------- #include \main() {

int i,j,k=0; char s[255];

while((s[k]=getchar())!='@') k++; for(j=0;s[j]!='@';j++)

9

2.---------------------------------------------------- #include \#include \main() { char str1[50]=\ char str2[50]=\

{ if(s[j]<='Z'&&s[j]>='A') { s[j]+=32; } if(s[j]<='w'&&s[j]>='a') s[j]+=3; else if(s[j]=='x'||s[j]=='y'||s[j]=='z') s[j]-=23; }

printf(\译码后结果:\for(i=0;s[i]!='@';i++) printf(\printf(\getchar(); }

===================== 实验八 函数

=====================

8.1？？？？？？？？？？？？？？？？？？？未成功 int a=3,b=5; max(int a,int b) { int c; c=a>b?a:b; return (c); }

main() { extern int a,b; printf(\} 8.2

#include int is_prime(int m) { int i; if(m==1) return 0; for(i=2;i

void main() { int n,c; scanf(\ c=is_prime(n);

6.--------------------------------------------------------

#include \main() {

int i=0;

char str1[255],str2[255]; printf(\scanf(\

printf(\scanf(\

while(1) { if(str1[i]==str2[i]) { i++; continue; } else break; }
