Answer:
The program to this question can be given as:
Program:
#include <stdio.h> //include header file.
int main() //defining main method
{
char i,j; //defining variable
for (i='a'; i<='e'; i++) //outer loop for column
{
for (j='a'; j<='e'; j++) //inner loop for row
{
printf("%c%c\n",i,j); //print value
}
}
return 0;
}
Output:
image.
Explanation:
- In the above C language program, firstly a header file is included. Then the main method is defined in this, a method contains a char variable that is "i and j". This variable is used in for loop, that is used to print the pattern.
- To print the following patter two for loop is used the outer loop is used for print columns and the inner loop prints row.

B, Parallel ports are faster than serial ports.
A parallel port can move a set of 8 bits at a time on eight different wires, it uses a 25 pin connector, called a DB-25 connector, whereas a serial port only has a DB-9 connector.
Abraham Lincoln was known as the Great Emancipator because of his actions both during and after the Civil War. Lincoln was opposed to slavery and wanted it abolished. However, many historians contend that, because he did not action his opposition to slavery, he does not deserve the title of the Great Emancipator.
