plz tell me the coding of this question

Question

Q:Write a C function to receive an integer of 3 digits then calculates and returns the sum of the MSD and the LSD. For example if your function received 345 it should return 8 ?

Answer 1

You can use the following function

unsigned int SumOfFirstAndThirdDigit(unsigned int Num)
{
    if(Num > 999) Num = 999;
   
    return ((Num / 100) + (Num % 10));
}

Answer 2

#include <stdio.h>

int main()
{
    printf("Enter a three digit number\t");
    int n;
    scanf("%d",&n);
    if(n>=101 && n<=999)
    {
        printf("%d",(n/100)+(n%10));
    }
    else
    {
        printf("Enter a valid three digit number");
    }

    return 0;
}

y dont u take  100 in if condition

---

#include <stdio.h>
#include<math.h>
int main(int argc,char* argv[])
{
    int n=atoi(argv[1]);
    int s,a=0,r,p,k;
    k=n;
    while(n>0)
    {
        r=n%10;
        n=n/10;
        a++;
    }
    p=a-1;
    s=(k/pow(10,p))+(k%10);
    printf("%d",s);
    
}//this code is efficient for any number

Exactly because 100 is also a three digit number

Answer 3

#include<stdio.h>

int main(){

int sum=0,a,b,n,d,raj,nick;

scanf("%d",&n);

nick=n;

while(n>0){

raj=n%10;

sum=raj+sum*10;

n=n/10;

}

a=nick%10;

b=sum%10;

d=a+b;

printf("%d",d);

return0;

}

Answer 4

int digits_sum(int num) {

if(num>99 && num<1000) {

return ((num%10) + (num/100));

}

}
