How to program: input three numbers to determine whether a triangle is formed

The sum of any two sides is greater than the third side
The difference between any two sides is less than the third side
A,B,C>0
A+B>C
A+C>B
B+C>A
|A-B|

C language program print digital character pattern, input any integer n, output n lines of triangle character array figure
For example, input integer 7 (Note: n should not be greater than 10), the program running results are as follows:
0 1 2 3 4 5 6
7 8 9 0 1 2
3 4 5 6 7
8 9 0 1
2 3 4
5 6
seven

#include<stdio.h>int arr[10] = {0,1,2,3,4,5,6,7,8,9};int main(){    int line , i , j , k = 0  ;&n...

How to judge whether the length of the three sides can form a triangle?

Input and then judge? Are you learning programming? Then compare, with loop, the sum of the two numbers is greater than the third number, the difference between the two numbers, light rain the third number, if all meet that
