What is the use of ternary operator in c language

The ternary operator is also known as: ternary operator and conditional operator. It is used to execute code based on the result of a binary condition. It can effectively reduce the number of lines of code and improve the performance of the application.

Ternary operator in c language

The ternary operator has the following form:

表达1？表达2：表达3

Description: Expression 1 represents the condition, Expression 2 and Expression 3 will be values ​​or variables or statements or any mathematical expressions. If expression1 evaluates to true, expression2 will be executed, otherwise expression3 will be executed.

Example:

a < b ？printf （“最小值为：a” ）：printf （“最小值为：b”）;

If the result of (a < b) is true, then return "the minimum value is: a"; otherwise, return "the minimum value is: b".

Flowchart:

Description: The ternary operator takes a binary condition as input, making it similar to an "if-else" control flow block . However, it also returns a value and behaves like a function.

Example of using ternary operator

#include<stdio.h>
 
  int main() {
    int a, b, max;
 
    printf("输入任意2个数字: \n");
    scanf("%d%d", & a, & b);
    /* Following statement replaces the whole if-else statement and makes the code more concise*/
    max = (a > b) ? a : b;
    printf("最大数字是：%d", max);
 
    return 0;
  }
