Question

write a program by for loop

Answer 1

I hope this is the standard example.

Sometimes we call the customer service via mobile, then it asks us to select an option from the menu. Upon selecting a menu item, we will be taken to concerned services. Here, if we don't select any services, it just hangs out. So the condition(menu) must be displayed, before its usage.

Ex:

char selection;

do{

System.out.println("Menu Items");

System.out.println("Press 1 for Mobile");

System.out.println("Press 2 for Data");

System.out.println("Press 3 for Complaints");

selection=(char) System.in.read();

}while(selection<'1' || selection>'3');

switch(selection){

case 1:

default:

}

Answer 2

Program to print following output

Output:

B

B  L

B  L  U

B  L  U  E

B  L  U  E  J

Explanation:

Following are the program in the Python Programming Language:

#set string type variable

str="BLUEJ"

#set for loop for row

for i in range(len(str)+1):

 #set for loop for column

 for j in range(i):

   #print message with space

   print(str[j], end="  ")

 #for line break

 print("\n")

Following are the description of the program:

• Firstly, set a variable 'str' and initialize the string data that variable.
• Set the two for loop for the row and column, the first for loop for the row and the second for loop for the column.
• Finally, print the output with space and then again use the print function to break the line for the following format.
