Problem statement

In this problem, we have to find the initials of a name. Given a name N, we have to print the initials of the name followed by the full surname.

For example, if N = Ram Kumar Sharma, then the initials will be:
R.K.Sharma

We will implement this problem in C Programming Language.

Approach to solve

Following is the approach to solve the problem:

  • First we take the input of the name in a variable named name.
  • Then we start a for loop and measure the length of the name by given the condition that name[i] is not equal to the new line character.
  • We initialise a variable len with the value 0 and increment it till it satisfies the above condition.
  • Now we count the number of spaces, for that we give the condition that name[i] is equal to space. If true variable count will be incremented by 1.
  • Now we again start a for loop from 0 to len.
  • First we print the first letter by name[0] then break the loop.
  • Now we start another loop from 0 to len. We then check if name[i] is equal to space or not. If true then we check if c is less than count or not(we create a variable c at the beginning of the program and initialise it with a value 1).If this is true then we print name[i+1] that is the character after space and increment the value of c by 1.If the above condition is false then it exits the loop and enters the next loop.
  • In the next loop we again check for a space, if true we had initialised a variable d with 0 at the beginning of the program, we increment it by 1.
  • Now if d is equal to count, then we print name[i+1] that is the character after space.

Implementation

Following is the implemention of the code in C programming language:

#include<stdio.h>
int main(int argc, char** argv)
{
	char name[100];
	int count=0,len=0,c=1,d=0;
	printf("Enter the name");
	scanf("%[^\n]s",name);
	int i;
	for(i=0;i<100;i++)
	{
		if(name[i]!='\n')
		{
			len++;
		}
		if(name[i]==' ')
		{
			count++;
		}
	}
	for(i=0;i<len;i++)
	{
		printf("%c.",name[0]);
		break;
	}
	for(i=0;i<len;i++)
	{	
		if(name[i]==' ')
		{
			if(c<count)
			{
				printf("%c.",name[i+1]);
				c++;
			}
			
		}
	}
	for(i=0;i<len;i++)
	{	
		if(name[i]==' ')
		{
			d++;
		}
		if(d==count)
	
		{
			printf("%c",name[i+1]);
		}
	}
	
	return 0;
}

Output

Run the code as follows:

gcc code.c
./a.out

Following is the output of the program:

Enter the name Ram Kumar Sharma
R.K.Sharma
