Write a program that uses nested loop or for statements to display Pattern A below, followed by an empty line and then another s

JulsSmile [24]

Answer:

public class Pyramid {

public static void main(String[] args) {

int h = 7;

System.out.println("Pattern A");

for(int i = 1; i <= h; ++i)

{

for(int j = 1; j <= i; ++j) {

System.out.print("+");

}

System.out.println();

}

System.out.println();

System.out.println("Pattern B");

for (int i = 1; i<=h; ++i)

{

for(int j = h; j >=i; --j){

System.out.print("+");

}

System.out.println();

}

Explanation:

The trick in this code is using a nested for loop
The outer for loop runs from i = 0 to the heigth of the triangle (in this case 7)
The inner for loop which prints the (+) sign runs from j = 0 to j<=i
It prints the + using the print() function and not println()
In the pattern B the loop is reversed to start from i = height

puteri [66]

Answer:

In Python:

def MPH(miles,minutes):

mph = round(60 * miles/minutes,1)

return mph

miles = float(input("Miles: "))

minutes = float(input("Minutes: "))

if miles>0 and minutes>0:

print("MPH: ",MPH(miles,minutes))

else:

print("Positive inputs only")

Explanation:

This defines the function

def MPH(miles,minutes):

This calculates mph rounded to 1 decimal place

mph = round(60 * miles/minutes,1)

This returns the calculated mph

return mph

The main begins here

This gets input for miles

miles = float(input("Miles: "))

This gets input for minutes

minutes = float(input("Minutes: "))

If miles and minutes are positive

if miles>0 and minutes>0:

This calls the MPH function

print("MPH: ",MPH(miles,minutes))

If otherwise, this prompts the user for positive inputs

<em> print("Positive inputs only")</em>
