⑶ 求帮忙编写这个C语言程序
#include<stdio.h>
#include<math.h>
void main()
{
float a,b,c,d;//a,b,c为系数
printf("请输入方程的三个系数：\n");
scanf("%f %f %f",&a,&b,&c);
d=b*b-4*a*c;
if(d>0)
printf("2");
else if(fabs(d)==0)
printf("1");
else if (a==0&&b==0&&c==0)
printf("-1");
else
printf("0");
return 0;
}
⑷ C语言程序编写
C语言使用 Xcode。Xcode 是由Apple官方开发的IDE,支持C、C++、Objective-C、Swift等
⑸ c语言怎么编写
#include<stdio.h>
#include<string.h>
#include<stdlib.h>
char fun(char *a,char *b)
{
char *t;
strcpy(t,a);
strcpy(a,b);
strcpy(b,t);
}
struct st{
char a[6][20];
};
int main()
{
struct st s[111];
int n,x[111],k=0,ts,sum=0;
scanf("%d",&n);
printf("学号 姓名 数学 物理 英语 计算机 ");
for(int i=0;i<n;i++)
{
sum=0;
for(int j=0;j<6;j++)
{
scanf("%s",s[i].a[j]);
if(j!=0&&j!=1)
{
sum+=atoi(s[i].a[j]);
}
}
x[k++]=sum/3;
}
for(int i=0;i<k;i++)
{
for(int j=0;j<k-i-1;j++)
{
if(x[j]>x[j+1])
{
ts=x[j];
x[j]=x[j+1];
x[j+1]=ts;
for(int l=0;l<6;l++)
fun(s[j].a[l],s[j+1].a[l]);
}
}
}
printf("学号 姓名 数学 物理 英语 计算机 平均成绩 ");
for(int i=0;i<n;i++)
{
for(int j=0;j<6;j++)
{
printf("%s",s[i].a[j]);
for(int k=0;k<8-strlen(s[i].a[j]);k++)
printf(" ");
}
printf("%8d ",x[i]);
}
return 0;
}
⑹ 编写c语言程序
#defineN10
#include<stdio.h>
#include<conio.h>
intmenu(){
printf(" ");
printf("=========菜单========== ");
printf(" 1.....初始化 ");
printf(" 2.....输入数据 ");
printf(" 3.....排序 ");
printf(" 4.....输出 ");
printf(" 0.....退出 ");
printf("请选择 ");
}
intinit(inta[],intn){
printf("数据初始化开始 ");
for(inti=0;i<n;i++)
a[i]=0;
printf("数据初始化结束 ");
}
intinput(inta[],intn){
printf("开始输入数据 ");
for(inti=0;i<n;i++)
scanf("%d",&a[i]);
printf("输入数据结束 ");
}
intprint(inta[],intn){
printf("开始输出数据 ");
printf("数组的数据如下 ");
for(inti=0;i<n;i++)
printf("%d",a[i]);
printf(" ");
printf("数据输出结束 ");
}
intsortit(inta[],intn){
inti,j,t;
printf("开始排序 ");
for(i=0;i<n-1;i++)
for(j=i+1;j<n;j++)
if(a[i]<a[j]){
t=a[i];a[i]=a[j];a[j]=t;
}
printf("排序结束 ");
}
intmain(){
inta[N];
charch;
menu();
while(1){
ch=getch();
switch(ch){
case'1':init(a,N);menu();break;
case'2':input(a,N);menu();break;
case'3':sortit(a,N);print(a,N);menu();break;
case'4':print(a,N);menu();break;
case'0':return0;

⑺ C语言程序编写代码，帮忙大神编写
(1)
#include"stdio.h"
#defineN10
intmain(intargc,char*argv[]){
FILE*fp,*fout;
charch,i;
fout=fopen("f2.txt","w");
if(fout==NULL||(fp=fopen("f1.txt","w+"))==NULL){
printf("Failedtocreatethefileandexit... ");
return0;
}
printf("Pleaseenterastring... ");
for(i=0;i<N;i++){
fputc(ch=getchar(),fp);
if(ch==' ')
break;
}
rewind(fp);
for(i=0;(ch=fgetc(fp))!=EOF;i++)
if((i+ch)&1)
fputc(ch,fout);
fclose(fp);
fclose(fout);
return0;
}
⑻ 如何编写C语言程序
C语言中，程序文件本身是文本格式，如果只是查看代码的话，可以这样做：打开记事本，使用文件中的“打开”菜单。在弹出的对话框中选择文件类型为“所有文件”，然后再浏览到程序文件，点击打开。但是如果需要在编译器环境中进行调试或编译等操作，则必须使用编译器，编译器必须使用与C语言文件在编写时使用的环境要求，不同的编译器提供的库函数不同，不能混用。
⑼ 用C语言编写程序，急用，非常感谢！
#include <stdio.h>
void jiami(FILE *fp,FILE *fp1)
{ unsigned char c,c1;
while(fscanf(fp,"%c",&c)==1)
{ c1=c/16+c%16*16;
fprintf(fp1,"%c",c1);
}
fclose(fp);
fclose(fp1);
}
void jiemi(FILE *fp,FILE *fp1)
{ jiami(fp,fp1);
}
int main()
{ int a,b;
FILE *fp,*fp1,*fp2;
fp=fopen("0.cpp","r");
fp1=fopen("jiami.txt","w");
jiami(fp,fp1);
fp=fopen("jiami.txt","r");
fp1=fopen("jiemi.txt","w");
jiemi(fp,fp1);
printf("加密文件是jiami.txt，解密文件是jiemi.txt，请查看\n");
return 0;
}
⑽ 帮忙写一段简单的c语言代码
#include <stdio.h>

{
FILE *fp;
int a[3][9],i,j;
if((fp=fopen("C:\cDemo\data.txt","r"))!=NULL)
{
for(i=0;i<3;++i)
{
for(j=0;j<9;++j)
{
fscanf(fp,"%d",&a[i][j]);
}
}
for(i=0;i<3;++i)
{
for(j=0;j<9;++j)
{
printf("%d ",a[i][j]);
}
printf(" ");
}
}
else
{
puts("Can't open C:\cDemo\data.txt");
}
return 0;
}
