1.输入语句:scanf("控制格式",接受值列表),其中控制格式常用的有:%d,%c,%s,%f,分别表示整型,字符型,字符串和浮点型.
例如int
achar
cscanf("%d
%c",&a,&c)表示向a和c输入值
2.赋值语句:=号,如将b赋值为10,为b=10
3.条件:if(布尔表达式){程序}else{程序}(注:此结构可嵌套)
switch(离散量){case
常量:...case
常量:...}
例:int
ascanf("%d",&a)
if(a>10)
{printf("大于10")}
else
{printf("小于10")}
例:switch(months)
{
case
1:printf("1月有31天")break
case
3:printf("3月有31天")break
....
default:break
}
4.循环:for结构,while结构,do-while结构
for(初始化判断变化)
{
}
while(条件)
{
}
do
{
}while(条件)
printf("n=%uP[%u]=%f\n",&n,&n,&P[n])//这个输出的是n和P[n]的地址.改成
printf("n=%dP[%d]=%f\n",n,n,P[n])
