c語言教學小學生

『壹』 小學生學編程入門先學什麼

可以自學scratch. Dk有本入門書

『貳』 c語言編程，小白求教，關於小學生計算輔助教學系統的改善

#include <stdio.h>
#include <stdlib.h>
#include <time.h>

int main (void)
{
int a,b,c,d,counter1=0;
float counter;

srand(time(NULL));
do{
counter=0; //這里改了
for(counter1=0;counter1<10;counter1++)
{
a=1+rand()%(10);
b=1+rand()%(10);
c=1+rand()%(4);
switch(c)
{

case 1:
printf ("%d X %d = ?",a,b);
scanf("%d",&d);
if(d==a*b)
{
printf("Right!\n");
counter++;
}
else
printf("Wrong!\n");
break;

case 2:
printf ("%d + %d = ?",a,b);
scanf("%d",&d);
if(d==a+b)
{
printf("Right!\n");
counter++;
}
else
printf("Wrong!\n");
break;

case 3:
printf ("%d - %d = ?",a,b);
scanf("%d",&d);
if(d==a-b)
{
printf("Right!\n");
counter++;
}
else
printf("wrong!\n");
break;

case 4:

『叄』 小學生怎麼學C語言

小學生？什麼生都是一樣的，只要你耐下心來，從第一頁慢慢看下去就行，不是太難理解，狂人C是啥書我不知道，但C語言有幾本入門的好書，名字我忘了，你可以到網上查查，最好是翻譯的國外書，國內的大學教材看不得。

『玖』 小學生如何學習c語言

要學習 C 語言，關鍵要懂英文。不懂英文，什麼都別談。

網上都有的教程，按照教程一步一步看，自己試著編一些簡單的程序，體會編程的快樂。

如果用的 Win-TC，要用

system("graftabl936");

將輸出語言換成中文。否則，當你想輸出中文時，輸出的卻是亂碼。

如果用的 Win-TC，要在程序最後添加

getch();

暫停屏幕，以查看輸出結果。否則，剛輸出完，程序就結束了，窗口也關閉了，什麼也看不到。
