C/Language Basics/Operator Ternary

Add function to the Ternary operator

<source lang="cpp">

1. include <stdio.h>

int f1(int n); int f2(void); int main(void) {

 int t;
 printf("Enter a number: ");
 scanf("%d", &t);
 /* print proper message */
 t ? f1( t ) + f2() : printf("No zero please.");
 printf("\n");
 return 0;

} int f1(int n) {

 printf("%d ", n);
 return 0;

} int f2(void) {

 printf("entered ");
 return 0;

}

      </source>

Operator which accepts three value

<source lang="cpp">

1. include <stdio.h>

int main(void) {

 int isqrd, i;
 printf("Enter a number: ");
 scanf("%d", &i);
 isqrd = i>0 ? i*i : -(i*i);
 printf("%d squared is %d", i, isqrd);
 return 0;

}

      </source>

Simple Ternary operator

<source lang="cpp">

1. include <stdio.h>

int main(void) {

 int i;
 printf("Enter a number: ");
 scanf("%d", &i);
 i = i > 0 ? 1: -1;
 printf("i =  %d", i);
 return 0;

}

      </source>

Ternary (?) operator

<source lang="cpp">

1. include <stdio.h>

void main() {

 const double price = 3.50; 
 const double discount1 = 0.05;  /* Discount for more than 10 */
 const double discount2 = 0.1;   /* Discount for more than 20 */
 const double discount3 = 0.15;  /* Discount for more than 50 */
 double total = 0.0;
 int quantity = 0;
 printf("Enter the number that you want to buy:");     /* Prompt message */
 scanf(" %d", &quantity);                             /* Read the input */
 total = quantity * price * ( 1.0 - (quantity>50 ? discount3 :
      (quantity>20 ? discount2 : (quantity>10 ? discount1 : 0.0))));
 printf("The price for %d is $%.2lf\n", quantity, total); 

}

      </source>

Ternary operator inside if else

<source lang="cpp">

1. include <stdio.h>
2. include <stdlib.h>

int main(void) {

 int magic;
 int guess;
 magic = rand(); /* generate the magic number */
 printf("Guess the magic number: ");
 scanf("%d", &guess);
 if(guess == magic) {
   printf("** Right ** ");
   printf("%d is the magic number", magic);
 }
 else
   guess > magic ? printf("High") : printf("Low");
 return 0;

}

      </source>

Use ternary operator in printf

<source lang="cpp">

1. include <stdio.h>

int main(void) {

 int x = 5, y = 10;
 printf("Max of %d and %d is: %d\n", x, y, (x>y ? x : y));
 return 0;

}

      </source>

Write expression inside Ternary operator

<source lang="cpp">

1. include <stdio.h>
2. include <stdlib.h>
3. include <conio.h>

int main(void) {

 while(!kbhit()) 
     rand();
 rand() % 2 ? printf("H") : printf("T");
 return 0;

}

      </source>
