C

my program is not returning any value...when i try to solve this problem without using user defined function and use printf() to output the message "that triangle is valid or not" ,its working

What I have tried:

#include<stdio.h>
#include <stdbool.h>
bool triangle( int a,int b,int c);
int main(void){
    printf("enter three side of triangel to check if triangle exist\n");
     
    
    int x=get_int();
    int y=get_int();
    int z=get_int();
    
    triangle(x,y,z);
}
bool triangle( int a,int b,int c)
{
    if((a>0&&b>0&&c>0)&&(a+b>c&&b+c>a&&a+c>a)){return true;}
        
    
    else{ return false;}}
