C language program to find the maximum value among 3 numbers

1. Write a C language program that can input 3 numbers and find the largest number among them.

#include <stdio.h>

int main() {
    int num1, num2, num3;

    // 输入三个数
    printf("请输入三个整数，用空格分隔：");
    scanf("%d %d %d", &num1, &num2, &num3);

    // 找出最大值
    int max = num1;
    if (num2 > max) {
        max = num2;
    }
    if (num3 > max) {
        max = num3;
    }

    // 输出最大值
    printf("最大值是：%d\n", max);

    return 0;
}

2. Use C language to design the algorithm for the largest number among three numbers

#include <stdio.h>

int findMax(int a, int b, int c) {
    int max = a;
    if (b > max) {
        max = b;
    }
    if (c > max) {
        max = c;
    }
    return max;
}

int main() {
    int num1, num2, num3;

    // 输入三个数
    printf("请输入三个整数，用空格分隔：");
    scanf("%d %d %d", &num1, &num2, &num3);

    // 调用函数找出最大值
    int max = findMax(num1, num2, num3);

    // 输出最大值
    printf("最大值是：%d\n", max);

    return 0;
}

3. Beginners: How to output three numbers in C language The largest number among the numbers

#include <stdio.h>

int main() {
    int num1, num2, num3;

    // 输入三个数
    printf("请输入三个整数，用空格分隔：");
    scanf("%d %d %d", &num1, &num2, &num3);

    // 找出最大值
    int max = num1;
    if (num2 > max) {
        max = num2;
    }
    if (num3 > max) {
        max = num3;
    }

    // 输出最大值
    printf("最大值是：%d\n", max);

    return 0;
}

4. C language inputs three numbers and outputs the maximum and minimum values

#include <stdio.h>

int main() {
    int num1, num2, num3;

    // 输入三个数
    printf("请输入三个整数，用空格分隔：");
    scanf("%d %d %d", &num1, &num2, &num3);

    // 找出最大值
    int max = num1;
    if (num2 > max) {
        max = num2;
    }
    if (num3 > max) {
        max = num3;
    }

    // 找出最小值
    int min = num1;
    if (num2 < min) {
        min = num2;
    }
    if (num3 < min) {
        min = num3;
    }

    // 输出最大与最小值
    printf("最大值是：%d\n", max);
    printf("最小值是：%d\n", min);

    return 0;
}

Summary

1. (1) C language can find the maximum and minimum values ​​among multiple input numbers through conditional statements (if statements).
2. (2) Using functions to encapsulate algorithms is a good programming practice and helps code reuse and maintenance.
3. (3) The input and output functions scanf and printf are used for input and output on the console.

The above is the detailed content of C language program to find the maximum value among 3 numbers. For more information, please follow other related articles on the PHP Chinese website!
