Write a program in C to check whether a triangle is valid or not, when the three angles of the triangle is entered through the keyboard. A triangle is valid if the sum of all the angles is equal to 180 degrees

Write a program in C to check whether a triangle is valid or not, when the three angles of the triangle is entered through the keyboard. A triangle is valid if the sum of all the angles is equal to 180 degrees.

            #include <stdio.h>
            #include <conio.h>
            void main() {
                        int a,b,c,d;
                        clrscr();
                        printf("Enter the angles of triangle : ");
                        printf("\nFirst : ");
                        scanf("%d", &a);
                        printf("Second : ");
                        scanf("%d", &b);
                        printf("Third : ");
                        scanf("%d", &c);
                        d=a+b+c;
                        if(d==180){
                                    printf("\nThis is a VALID triangle");
                        } else {
                                    printf("\nThis ia NOT a VALID triangle");
                        }
                        getch();
            }
