C language program: judging triangles

Define a function , Judge whether the three reshaped side lengths can form a triangle , If it's a triangle , Then judge whether it is a right triangle .

1) Declare functions judge;

2) Implementation function judge, Judge whether a triangle can be formed according to the input three side lengths ;

3) stay main Call in judge;

4) stay main According to the judge The return value of determines whether it is a triangle , If it forms a triangle, it is further judged whether it is a right triangle , Output the corresponding result .

Problem analysis ：

（1） The key factor of triangle formation is the value of three sides , It is also the basis of our judgment

（2） So let's first write a judge Function to judge whether it can form a triangle , And return a similar bool Judgement of type , It is convenient to call the main function quickly

（3） Further in the main function “ Data groups that can form triangles ” Judge whether it can constitute “ right triangle ”

#include <stdio.h>
int judge(int x,int y,int z)
{
    int m;
    if (((x+y)>z)&&((x-y)<z)&&((x+z)>y)&&((x-z)<y)&&((y+z)>x)&&((y-z)<x))
        m=1;
    else
        m=0;
    return m;
}
main()
{
    int a,b,c,n;
    printf(" Please enter a,b,c：");
    scanf("%d%d%d",&a,&b,&c);
    n=judge(a,b,c);
    if (n==1)
        if (((a*a+b*b)==c*c)||((a*a+c*c)==b*b)||(b*b+c*c==a*a)) // Or condition to judge whether it is a right triangle 
            printf(" Can form a right triangle ");
        else
            printf(" Can form a triangle ");
    else
        printf(" Can't make a triangle ");
}
