一段小程序，如何读取一个TXT文档。 一个名为name的文档。# include "stdio.h"# include "iostream.h"# include "string.h"void main(){ //打开文件name.txt且为只读模式 //name.txt保存在当前文件夹下 FILE *file=fopen("name.txt","r");

①for循环类型 当知道循环次数时优先 例子：//求一到十的和`for(int i=1;i<=10;i++){sum+=i}`//双循环,求1到10的阶乘之和int i=0;int sum2=0;for(i=1;i<=10;i++){int sum1=1;for(int j=1;j<=i;j++){sum1*=j;}sum2+=sum1;}②while循环 知道循

如代码。int占有4个字节，char占有1个字节，float占有4个字节，idouble占有8个字节.# include "stdio.h"# include "iostream.h"//sizeof练习//不同类型所占用内存大小。void test1(){ int a=0; char b='a'; double c=0; float d=0; cou

注意：一个中文字占两个字符# include "stdio.h"# include "iostream.h"# include "string.h"//关于strlen函数,求括号里字符串的长度 void main(){ char a[10]={0}; char b[10]={'a','s','d'}; char c[10]="早上好"; cout<<strl

# include "stdio.h"# include "iostream.h"//快速排序void select_sort(int*a,int n){ register int i,j,min,t; for(i=0;i<n-1;i++) { min=i;//查找最小值 for(j=i+1;j<n;j++) i

# include "stdio.h"# include "string.h"# include "iostream.h"void main(){ //指针定义与赋值 int a=2; int * p=NULL; p=&a; cout<<a<<endl; cout<<&a<<endl; cout<<*p<<endl; cout<<

# include "stdio.h"# include "iostream.h"# include "malloc.h"# include "string.h"//关于函数赋值void fun1(int num1,int num2){ cout<<"fun1():"<<endl<<"num1="<<num1<<" "<<"num2="<<num2<<endl; int
