C PROGRAM TO FIND SUM OF SERIES

Code:

#include<stdio.h>
int main()
{
int i,N;
unsigned long sum;
printf("Enter the value of N: ");
scanf("%d",&N);
sum=0;
for(i=1;i<=N;i++)
sum= sum+ (i*i);
printf("Sum of the series is: %ld\n",sum);
return 0;
} 

Explanation: 

           

  • To find sum of series we get the required data from the user by using the statement "printf".
  • The next step is we are storing the user given data in some variable called "N".
  •  Then we are processing it using the above statements. 
  • Then to get the desired output we are printing the exact statement to be displayed again using printf statement.

output:

Use of Backslash "\n" in C language

-
 Why  Backslash "n" is used in "printf" in machine languages Answer: Backslash "\n" is used in many programming languages. It is called as newline character. We use Backslash "\n" to bring a newline in our output . This newline character is a type of escape sequence . This helps the programmer or the coder to display the output with an alignment . It also help others to see and understand  the output clearly. The Backslash "\n" is used only in "printf" statements There are also other escape sequence characters like "\t" . "\t" is use for tab space . It...

COHESION AND COUPLING material

  5.3 COHESION AND COUPLING   ●       We have so far discussed that effective problem decomposition is an important characteristic of a good design. ●       Good module decomposition is indicated through high cohesion of the individual modules and low coupling of the modules with each other. ●       Cohesion is a measure of the functional strength of a module, whereas the coupling between two modules is a measure of the degree of interaction (or interdependence) between the two modules. ●       Coupling: Intuitively, we can think of coupling as follows.   ●       Two modules are said to be highly coupled, if either of the following two situations arise: ●       If the function calls between two modules involve passing large chunks of shared data, the modules are tightly coupled ●     ...
