Answer:
There are different phases of railroad expansion with the innovations in technology.
Explanation:
Few of the technological innovations are described below that leads in railroad expansion more rapid.
1. Centralized Traffic control (CTC) is introduced in 1960's that is used to control the traffic on railroads using different signal control.
2. In 1990's after computer technology involvement, railway ticket and reservation system is automate and being centralized. That makes the railroad expansion improve.
3. Bullet train technology has been introduced, that makes the railway trains more faster.
4. Electric trains has been introduced to use green energy and reduce the dependency on the fuel to make environment clean and green.
Answer:
Multiple devices can be connected
Answer:
b=0
c=0
lol=list()
while True:
salary=input("Enter your salary: ")
if salary=="e" or salary=="E":
print("Thankyou!!")
break
else:
a=int(salary)
if a>=300000 and a<=400000:
c=c+1
if a<0 or a>400000:
print("Your salary is either too small or too big ")
if a>0 and a<=400000:
a=a-(25/100*a)-(5/100*a)-(2/100*a)
lol.append(a)
b=b+1
if a>=300000:
c=c+1
print(lol)
print("The number of salaries entered is: "+ str(b))
print("The number of salaries that exceeded 300000 is: "+str(c))
Answer:
//here is code in c++.
#include <bits/stdc++.h>
using namespace std;
int main()
{
// variable
int temp;
cout<<"Please enter the temperature:";
//read temperature from user
cin>>temp;
int n;
// reduce the case for switch
n=temp/10;
// print output according to the switch case
switch (n) {
case 7:
case 6:
cout<<"tennis"<<endl;
break;
case 5:
case 4:
cout<<"golf"<<endl;
break;
default:
if(temp>=80)
cout<<"swimming"<<endl;
else
cout<<"skiing"<<endl;
break;
}
return 0;
}
Explanation:
Read the value of temperature from user and assign it to variable "temp".
Calculate n=temp/10, to limit the number of cases in the switch statement.
if temperature is greater or equal 60 & less than 80, it will print "tennis".
If temperature is greater or equal 40 & less than 60, it will print "golf".
in default case, if temperature is greater than 80, it will print "swimming".
if less than 40, print "skiing".
Output:
Please enter the temperature::67
tennis
