用c语言如何编程?

Answer 1

#include <stdio.h>

{
int amount = 100;
int price = 0;

amount = 90;

scanf("%d", &price);

printf("你有多少");
scanf("%d",&amount);

int change = amount - price;

if(a>c){
printf("%c",a);
} else{
printf("%c",c);
}
} else{
if(b>c){
printf("%c",b);
} else{

Answer 3

建议从python入门，c语言需要很多计算机基础知识，并不适合编程入门。
