C Practice Q_29

Answer :

Do While Loop :

 #include<stdio.h>

int main ()

{

int num,num1;

do

{

    num1=num1+num;

    num++;

}

while (num<=10);

printf("%d\n",num1);

}

While Loop :

#include<stdio.h>

int main ()

{

int num=1,num1=0;

while (num<=10)

{

    num1=num1+num;

    num++;

}

printf("%d\n",num1);

}

For Loop :

#include<stdio.h>

int main ()

{

int num,num1;

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

{

num1=num1+num;

}

printf("%d\n",num1);

}

Output :
