Write a C Program to Find the Sum of Odd Numbers and Even Numbers from 1 to N by using if and for Statement

Data types:

• Data Type defines what Type of value you can store in a Variable.
• Primary Data Types: int ,float and char.

Float:

• Format Specifier = %f
• Keyword = float
• Space = 4 byte
• Range = 3.4 * 10^(38) to -3.4 * 10^(38)
• Decimal values are allowed. 

Statement of C Program: Enter a Number ( N ) and Calculate the Sum of Odd and Even Numbers From 1 to N :
 

#include<stdio.h>

#include<conio.h>

void main()

{

int i, N ;

oddsum=0;                                  

evensum=0;

clrscr();

printf(" Enter the value of N\n");

scanf("%d" , &N);

for( i=1 ; i<=N ; i++ )

{

if(i%2 ==0)

{

evensum=evensum+ i;

}

else

{

oddsum=oddsum+i;

}

}

printf(" Sum of Odd Numbers = %d" , oddsum);

printf(" Sum of Even Numbers = %d" , evensum);

getch()

}

Output:

Enter the value of N

10

Sum of Odd Numbers = 25

Sum of Even Numbers = 30
