456 sum is 15

Code
int sumDigits(int n) { 
int sum = 0; 
 
while( n > 0 ) { 
sum += (n % 10); // add last digit of n to sum 
n /= 10; // divide n by 10 to "chop off" the last digit 
} 
 
return sum; 
 
getch();
}

Code
#include<stdio.h>
#include<conio.h>
main()
{
        float f;
        int s,r,k=1;
        printf("Enter the number:=>");
        scanf("%f",&f);
        s=f/1;
        while(k==1)
        {
                r=s%10;
                printf("%d
",r);
                k++;
        }
        return 0;
} 

in the first if condition want to place double equal.then it will treat as condition.otherwise it will treat as declaration

C++ compiler treat Zero(0) as false and all nonzero value as true.
Consider the case 1:
if(val=20) //implicitly it becomes if(20)
{
cout<<"Control comes here.";
}
Case 2:
val=5;
if(val==5) //implicitly it becomes if(1) as condition is true
{
cout<<"here control comes.";
}

Yes th programming language is case sensitive because of its sensitivity that means the language itself having some built in keywords that are used to define variables and data types also vary accordi...

When a PL is case sensitive, the number of possible keywords/ variable names permissible is increased.

Also - more important reason - program readability is improved - we use caps for macros, have different naming conventions based on case sensitivity and so on.

Interfaces define a contract. You should use it only if you want to support a group or related functionalities in a class or struct. Otherwise there is no need to use it. Think about cars - they have ...

command line arguments are those which can be passed to the main method as parameters and use those values in the main method before executing it.
