A C program that find sum from 1 to 10

This is the program which uses the help of "For loop" to find the sum of the numbers from 1 to 10.

C Program:-

#include<stdio.h>

#include<conio.h>

void main(void)

{

clrscr();

int n,sum;

for(n=1;n<10;n++)

sum+=n;

printf("\n\nThe total from 1 to 10 is %d",sum);

getch();

}

Same Program in another Way:-

#include<stdio.h>

#include<conio.h>

void main(void)

{

clrscr();

int n,sum=0;

for(n=1;n<10;n++)

{

sum=sum+n;

printf("\n\ncount= %d  total= %d  ",n,sum);

}

printf("\n\nThe total from 1 to 10 is %d",sum);

getch();

}

Same program with setting the column width:-

#include<stdio.h>

#include<conio.h>

void main(void)

{

clrscr();

int count=1,sum=0;

while(count<=10)

{

sum+=count;

printf("\n\n count=%2d    sum= %2d",count,sum);

count++;

}

getch();

}

Note:-

              In this program we set the column width by "%2d" this with set the column with two digit place.
