我一直在尝试创建一个程序来确定:当给定一组具有最小角度的直角三角形时。但我遇到了很多困难,我推断如果a是边长,b和c是斜边,那么a

float a, b, c, a1, b1, c1;
float sinTheta, sinTheta1;

printf ("Please enter values for a, b, c\n");
scanf ("%f%f%f", &a, &b, &c);

printf ("Please enter values for a1, b1, c1\n");
scanf ("%f%f%f", &a1, &b1, &c1);


sinTheta=a/c;
sinTheta1=a1/c1;

if (sinTheta < sinTheta1)
printf ("the triangle a b c has the smaller angle\n");

else
if (sinTheta > sinTheta1)
printf ("The triangle a1, b1, c1 has the smaller angle\n");

return 0;

最佳答案

如果这是您的完整源代码,则某些部分会丢失。您可以导入<stdio.h>通过写

#include <stdio.h>

在代码的开头。

此外,没有main() { ... } 。您还可以处理两个角度相等的情况 sinTheta == sinTheta1 .

#include <stdio.h>

int main() {

float a, b, c, a1, b1, c1;
float sinTheta, sinTheta1;

printf ("Please enter values for a, b, c\n");
scanf ("%f%f%f", &a, &b, &c);

printf ("Please enter values for a1, b1, c1\n");
scanf ("%f%f%f", &a1, &b1, &c1);


sinTheta=a/c;
sinTheta1=a1/c1;

if (sinTheta < sinTheta1) {
printf ("the triangle a b c has the smaller angle\n");
}
else if (sinTheta > sinTheta1) {
printf ("The triangle a1, b1, c1 has the smaller angle\n");
}
else
{
printf ("the angles are the same\n");
}
return 0;
}

顺便说一句:b 的值是多余的。

编辑:

快速而肮脏的方法:

#include <stdio.h>

int main() {

float a, c;
float sinTheta;

float sinThetaMin;
int nMin;
int nTriangle=2; // specifies the number of triangles
int i;


for (i=0; i<nTriangle; i++) {
printf ("Please enter values for a, c for triangle %d\n", i+1);
scanf ("%f%f", &a, &c);
sinTheta = a/c;
printf("%f\n", sinTheta);
if (i == 0) {
sinThetaMin = sinTheta;
nMin = i+1;
}
else {
if (sinTheta < sinThetaMin) {
sinThetaMin = sinTheta;
nMin = i+1;
}
}

}

printf("Smallest triangle is number %d with a/c = %f\n", nMin, sinThetaMin);

return 0;
}
