[英]C program running an extra loop
Write a program that points to the table of values of a given function.编写一个程序,指向给定 function 的值表。 The initial value of x changes with step d, until the value of y (which is function of x) become greater than a number c
x 的初始值随着步骤 d 变化,直到 y 的值(即 x 的 function)变得大于一个数字 c
I have been trying to solve this task for some time but I always come across the same problem.我一直试图解决这个任务一段时间,但我总是遇到同样的问题。 The program always throws me one more value.
该程序总是给我带来更多价值。 See code.
见代码。 Thanks in advance.
提前致谢。
#include <stdio.h>
#include <math.h>
main(){
float x,d,y=0;
float c;
printf("Write begin and end of interval: ");
scanf("%f%f",&x,&c);
printf("Write step d: ");
scanf("%f",&d);
printf("x y\n");
while (c>y){
y=pow(x,2)+(1/sqrt(x+1));
printf("%.2f %.2f\n",x,y);
x+=d;
}
}
This is what program does这就是程序所做的
Write begin and end of interval: 1 5
Write step d: 0.5
x y
1.00 1.71
1.50 2.88
2.00 4.58
2.50 6.78 -------> this is undesired because y>c
Mathematical expression数学表达式
Just add an if
statement that checks for y after calculation.只需添加一个
if
语句,在计算后检查 y。 Note that you have to change it to c<=y
if you don't want y=c
to also not get printed.请注意,如果您不希望
y=c
也不被打印,则必须将其更改为c<=y
。
#include <stdio.h>
#include <math.h>
int main(){
float x,d,y=0;
float c;
printf("Write begin and end of interval: ");
scanf("%f%f",&x,&c);
printf("Write step d: ");
scanf("%f",&d);
printf("x y\n");
while (c>y){
y=pow(x,2)+(1/sqrt(x+1));
if(c<y){
break;
}
printf("%.2f %.2f\n",x,y);
x+=d;
}
}
