The C language-CodePudding

I the purpose of this program is to add 1 to 100, and is something wrong? Have a great spirit to give directions? A freshman C language for beginners!

CodePudding user response:

I want to know you I was used to record what of,

If I were starting position, so I=1, the output is 5050, and the answer is right,

 
# include & lt; Stdio. H> 

Void main () {
Int I, sum=0; 
Printf (" please enter an I value "); 
The scanf (" % d ", & amp; i); 
While (i<{
=100)Sum=I + sum; 
i++; 
} 
Printf (" sum=% d ", sum); 
}

If I was terminated position, so I=100, when the answer 5050.

 
# include & lt; Stdio. H> 

Void main () {
Int I, sum=0; 
Printf (" please enter an I value "); 
The scanf (" % d ", & amp; i); 
While (I) {
The sum +=I; 
I -; 
} 
Printf (" sum=% d ", sum); 
}

Can you tell anything wrong, and the correct letter to me have a look at it

CodePudding user response:

Look at the,
A=1, b=100
Sum=5050

 
# include & lt; Stdio. H> 

Void main () {
Int a, b, sum=0, I; 
The scanf (" % d % d ", & amp; A, & amp; B); 
For (I=a; I<=b; I++) sum +=I; 
Printf (" sum=% d ", sum); 
}

Your code:
I said if it is a starting position, that is right,
I said if it is terminated position, and that is wrong,

Right on the 1st floor back,

CodePudding user response:

And your third line should be:
Int I, sum=0;

To add a comma with a semicolon,
