Function Examples(Pass and No Return)

Question:3
Write a function C language to take input for 3 nos check and print largest number?
Sol:

#include <stdio.h>

//function definition
void largest(int p,int q,int r)
{
    int m;
    if(p>q && p>r)
        m=p;
    else
        if(q>r)
        m=q;
    else
        m=r;
    printf("max no = %d",m);
}
int main()
{
    int a,b,c;
    printf("Enter 3 nos ");
    scanf("%d %d %d",&a,&b,&c);
    largest(a,b,c);
    return 0;
}

Output:

Enter 3 nos 25
96
35
max no = 96

Question:4
Write a function C language to take input for a character check and print whether it an alphabet or not?
Sol:

#include <stdio.h>

#include <stdio.h>

//function definition
void alpha(char ch)
{
    if((ch>='A' && ch<='Z') || (ch>='a' && ch<='z'))
        printf("it is an alphabet");
    else
        printf("it is not an alphabet");
}
int main()
{
    char ch;
    printf("Enter any character ");
    scanf("%c",&ch);
    alpha(ch);
    return 0;
}
