Find the Largest Number Using if-else Statements
The idea is to use the compound expression where each number is compared with the other two to find out which one is the maximum of them.
Algorithm
- Check if A is greater than or equal to both B and C, A is the largest number.
- Check if B is greater than or equal to both A and C, B is the largest number.
- Check if C is greater than or equal to both A and B, C is the largest number.
C Program to Find the Largest Number Using if Statement
C
// C program to find the maximum number out of the three// given numbers using if-else statement#include <stdio.h>int main(){ int A, B, C; printf("Enter the numbers A, B and C: "); scanf("%d %d %d", &A, &B, &C); // finding max using compound expressions if (A >= B && A >= C) printf("%d is the largest number.", A); else if (B >= A && B >= C) printf("%d is the largest number.", B); else printf("%d is the largest number.", C); return 0;} |
Output
Enter the numbers A, B and C: 32764 is the largest number.
Complexity Analysis
- Time complexity: O(1) as it is doing constant operations
- Auxiliary space: O(1)
C program to Find the Largest Number Among Three Numbers
Here, we will learn how to find the largest number among the three numbers using the C program. For example, the largest number among 2, 8, and 1 is 8.
