How do you code an even number?
If a number is evenly divisible by 2 with no remainder, then it is even. You can calculate the remainder with the modulo operator \% like this num \% 2 == 0 . If a number divided by 2 leaves a remainder of 1, then the number is odd. You can check for this using num \% 2 == 1 .
How do you find the sum of even numbers in QBasic?
QBasic Programming
- FOR I = 1 TO 10. INPUT “ENTER THE NUMBERS”; N(I) IF N(I) MOD 2 = 0 THEN S = S + N(I) NEXT I.
- USING SUB PROCEDURE. DECLARE SUB SUM (N( )) FOR I = 1 TO 10.
- SUB SUM (N()) FOR I = 1 TO 10. IF N(I) MOD 2 = 0 THEN S = S + N(I)
- USING FUNCTION PROCEDURE. DECLARE FUNCTION SUM (N( )) FOR I = 1 TO 10.
Which sum is an even number?
Also, find sum of odd numbers here….Sum of First Ten Even numbers.
| Number of consecutive even numbers (n) | Sum of even numbers (Sn = n (n+1)) | Recheck |
|---|---|---|
| 4 | 4(4+1) = 4 x 5 = 20 | 2+4+6+8=20 |
| 5 | 5(5+1) = 5 x 6 = 30 | 2+4+6+8+10 = 30 |
| 6 | 6(6+1) = 6 x 7 = 42 | 2+4+6+8+10+12 = 42 |
| 7 | 7(7+1) = 7×8 = 56 | 2+4+6+8+10+12+14 = 56 |
What is the general formula of even numbers?
A formal definition of an even number is that it is an integer of the form n = 2k, where k is an integer; it can then be shown that an odd number is an integer of the form n = 2k + 1 (or alternately, 2k − 1).
What is if else write a program to check number is odd or even?
In the program, the integer entered by the user is stored in the variable num . Then, whether num is perfectly divisible by 2 or not is checked using the modulus \% operator. If the number is perfectly divisible by 2 , test expression number\%2 == 0 evaluates to 1 (true). This means the number is even.
How do I write a Qbasic program?
Creating a Program Using the QBASIC Editor Click the Start button to display the Start menu. Point to Programs. Choose MS-DOS Prompt and an MS-DOS Prompt window opens. At the C:\> prompt (or at the C:\Windows> prompt), type QBASIC and press the ENTER key and the QBASIC editor appears.
How do you find the factors of a number in Qbasic?
QBasic Programming
- INPUT “ENTER ANY NUMBER”; N. S = 0. FOR I = 1 TO N. IF N MOD I = 0 THEN S = S + I.
- DECLARE SUB FACT (N) INPUT “ENTER ANY NUMBER”; N. CALL FACT (N)
- SUB FACT (N) S = 0. FOR I = 1 TO N.
- DECLARE FUNCTION FACT (N) INPUT “ENTER ANY NUMBER”; N. PRINT “SUM OF FACTORS=”; FACT (N)
- FUNCTION FACT (N) S = 0. FOR I = 1 TO N.
How to perform arithmetic operations in COBOL?
In COBOL, Arithmetic operations are performed in PROCEDURE DIVISION. Arithmetic operations are performed using these major verbs- 1. ADD 2. SUBTRACT 3. MULTIPLY 4. DIVIDE 5. COMPUTE It is used to perform an addition of 2 or more numeric literals or 2 or more numeric variables.
How to execute the above COBOL program using JCL?
JCL to execute the above COBOL program. When you compile and execute the above program, it produces the following result − Add verb is used to add two or more numbers and store the result in the destination operand. In syntax-1, A, B, C are added and the result is stored in C (C=A+B+C).
How do you convert COBOL to machine language?
One must understand the way COBOL works. Computers only understand machine code, a binary stream of 0s and 1s. COBOL code must be converted into machine code using a compiler. Run the program source through a compiler. The compiler first checks for any syntax errors and then converts it into machine language.
Where can I try COBOL for free?
Tutorials point is one amazing place to try out COBOL programs in real time. Of course, JCL’s cant be tried as you need an actual mainframe. I’m not too sure how the current free emulators for mainframe works. I had a tough-luck find one that’s actually working. I shall also try sharing a more advanced programs. Watch out in this space.
