Characteristics of computers

• Speed Computers process data at extremely fast rate, at millions of instructions per second. A computer can perform a huge task that a normal human being may take days or even years to complete. The speed of a computer is calculated in MHz (MegaHertz) ie. One Million instructions per second.

• 2. Accuracy Computers are very accurate. The level of accuracy depends on the instructions and type of

machine being used. Faulty instructions for data processing lead to faulty results. This is called

GIGO (Garbage In Garbage Out).Computer’s physical circuits rarely make errors, if the data and

instruction are correctly fed. Most of the errors occurring in computers are either hardware errors

or human errors.

Scientific Notation

1. C2H6 + 3.5 O2 à 2 CO2 + 3 H2O

2. (X + Y)2 = X2 + Y2 + 2XY

RESULT

Thus the document has been created as per the format given.

Step1: Start the program. Step2: Initialize the variable as zero. Step3: If the number is not equal to zero then the corresponding operation will be performed. Step4: Print the sum of the digits, reverse of the number. Step5; check whether the number is palindrome or not. Step6: stop the program.

PROGRAM

#include<stdio.h> main() { unsigned long int a,num,sum=0,rnum=0,rem; clrscr(); printf("\nEnter the number..."); scanf("%ld",&num); a=num; while(num!=0) { rem=num%10; sum=sum+rem; rnum=rnum*10+rem; num=num/10; } printf("\nThe sum of the digits of %ld is %ld\n",a,sum); printf("\nThe reverse number of the %ld is %ld",a,rnum); if(a==rnum) printf("\nThe given number is a palindrome"); else printf("\nThe given number is not a palindrome"); getch(); }

C.

ALGORITHM


Step2: Enter the size of the array.

AIM

To write a C program to perform menu driven program.

ALGORITHM


Step2: Read the values of num

Step3: Assign the value of 1 to Factorial similarly 2 to prime no, 3 to odd or

even and 4 to Exit.
