Question

5. 编写程序,设a=2,b=3,x=3.5,y=2.5计算并输出算术表达式(float)(a+b)/2+(int)x%(

4． 编写程序，设x=2.5，a=7，y=4.7计算并输出算术表达式x+a%3*（x+y）%2/4的值。

Answer 1

#include<stdio.h>
main() {
float x = 2.5, a = 7, y = 4.7;
printf("%f", x + a%3*(x+y)%2/4);
}
#include<stdio.h>
main() {
int a =2, b=3;
float x=3.5, y=2.5;
printf("%f", (float)(a+b)/2 + (int)x%y);
}

Answer 2

不知是用哪种编程语言编写？
用C就是这样:
题5
#include<stdio.h>
main() {
int a =2, b=3;
float x=3.5, y=2.5;
printf("%f", (float)(a+b)/2 + (int)x%y);
}
题4
#include<stdio.h>
main() {
float x = 2.5, a = 7, y = 4.7;
printf("%f", x + a%3*(x+y)%2/4);
}

Answer 3

5.
include<stdio.h>
main()
{
int a=2,b=3;
float x=3.5,y=2.5,s;
s=(float)(a+b)/2+(int)x%y
printf("%f",s);
}
4.
#include<stdio.h>
main()
{
int a=7;
float x=2.5,y=4.7,s=0;
s=x+a%3*(x+y)%2/4;
printf("%f",s);
}

Answer 4

#include<studio.h>
main()
{
int x,a,y,z:
x=2.5;
a=7;
y=4.7'
z=x+a%3*（x+y）%2/4'
prinft("d%"，z)；

}
