编写一个程序，编写一个C程序

经验分享生活百科

1，编写一个C程序#include<stdio.h>int main()int n,i,s,t=1;scanf("%d", &n);while(n<0 || n%2==0) printf("请重新输入一个奇数!\n");scanf("%d", &n);}for(i=1;i<=n;i++)t=t*i;if(i%2==1)s+=t;}}printf("%d", s);return 0;}
2，编写一个程序#include<iostream>#include<string>using namespace std;int main() int i,count; string d[5] ; cout << "Input a sentence with 5 words: " ; for( i = 0; i < 5; i++ ) cin >> d[i]; cout << "Input the number of the word you want to print: "; cin >> count; cout << d[ count-1 ] << endl; return 0;}
3，编写一个程序vb.net中实现代码：Private Sub TextBox1_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox1.TextChangedStatic i = 0Dim kk As String = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ"If InStr(kk, TextBox1.Text.Substring(i, 1)) ThenTextBox2.Text = TextBox2.Text & TextBox1.Text.Substring(i, 1)ElseTextBox2.Text += "*"End Ifi += 1End Sub【编写一个程序，编写一个C程序】
4 ， 编写一个程序#include <stdio.h>int fun(int n) int i,t; t = 1; for(i=1; i<=n; i++) t = 2 * t; } return t;}int main() int i,n,sum; sum = 0; i = 1; while(sum<1000) sum += fun(i); i++; } n = i - 2; printf("最大的n的值是:%d\n",n); return 0;}#include <stdio.h>int fun(int n) int i,t; t = 1; for(i=1; i<=n; i++) t = 2 * t; } return t;}int main() int i,n,sum; sum = 0; i = 1; while(sum<1000) sum += fun(i); i++; } n = i - 2; printf("最大的n是:%d\n",n); return 0;}#include <stdio.h>int fun(int n) int i,t; t = 1; for(i=1; i<=n; i++)t = 2 * t; } return t;}main() int i,n,sum; sum = 0; i = 1; while(sum<1000)sum += fun(i);i++; } n = i - 2; printf("当%d是时，符合要求\n",n); return 0;}5，编写一个程序#include#include void main() { char a[100]; int b; gets(a); scanf("%d",&b); if(b#include #include using namespace std; int main() { char in[100]; //可改 int n; cout<<"please putin :"<>in; cin>>n; cout<<import java.util.Scanner;public class dis { public static void main(String[] args) {Scanner input=new Scanner(System.in);System.out.print("请输入一个字符串:");String word=input.next();System.out.print("请输入一个数字，输出字符串中对应的字符:");int num=input.nextInt();if(nummain() { char *str; int n; printf("Please input a string:"); scanf("%s",str); printf("Which char:"); scanf("%d",&n); printf("The NO.%d charector is \"%.1s\" ",n,str+n-1); getch(); }#include #include void main() { int num = 0; char buf[1024]; ZeroMemory(buf, sizeof(buf)); printf("Please input a string:"); scanf("%s", buf); printf("Please input a num:"); scanf("%d", &num); printf("pos:%d char:%c\n", num, buf[num-1]); }
