Question

1) Use a loop structure to calculate the sum of all odd numbers from 1 to 15

2) Use a loop structure to calculate the product of all odd numbers from 1 to 9.

3) Write a program to convert US dollars to Bangaldeshi taka

Answer 1

#include<stdio.h>

#include<conio.h>

int main()

{

int i;

int sum=0;

int odd[16];

for(i=0;i<16;i++)

{

odd[i]=i;

}

for(i=0;i<16;i++)

{

if(odd[i]%2!=0)

sum=sum+i;

}

printf("Sum=%d",sum);

return 0;

}//Output :Sum=64

if you are doing coding in Turbo c you can use clrscr():-clear the screen

2)

#include<stdio.h>
#include<conio.h>
int main()
{
int i;
int pro=0;
int odd[10];
for(i=0;i<=9;i++)
{
odd[i]=i;
}
for(i=0;i<;i++)
{
if(odd[i]%2!=0)

pro =pro*i
}
printf("Product=%d",pro);
return 0;
}
//output: pro=945
