C programming simple if else example

We already discussed c programming control flow statement with various types in our earlier tutorial lets see few examples

C program to find the minimum value of 3 variable

/* simple if statement example */ 
#include <stdio.h> 
int main() 
{ 
    int x,y,z,min; 
    x=10; y=5; z=20; 
    if(x<y&&x<z) 
    { 
        min=x; 
    } 
    if(y<x&&y<z) 
    { 
        min=y; 
    } 
    if(z<x&&z<y) 
    { 
        min=z; 
    } 
    printf("Min value is:%d",min); 
    return 0; 
}

Output:

[quote]Min value is:5[/quote]

C program to find the maximum value of 3 input values

/* Nested if-else example */ 
#include <stdio.h> 
int main() 
{ 
    int a,b,c,d,max; 
    printf("Enter 4 values: "); 
    scanf("%d%d%d%d",&a,&b,&c,&d); //a=10; b=20; c=15; d=5; 
    if(a>b&&a>c&&a>d) 
    { 
        max=a; 
    } 
    else 
    { 
        if(b>c&&b>d) 
        { 
            max=b; 
        } 
        else 
        { 
            if(c>d) 
                max=c; 
            else 
                max=d; 
        } 
    } 
    printf("Max value is:%d",max); 
    
    return 0; 
}

Output:
