Answer:
Program is as follow:
Explanation:
#include<iostream.h>
#include < conio.h>
bool isVowel(char b)
{
return
( b=='a' || b=='A' || b=='e' || b=='E' || b=='i' || b=='I' || b=='o' || b=='O' || b== 'u' || b=='U');
For swaoing the vowels
string reverseVowel ( String str)
{
int j = 0;
string v ;
for ( int i= 0 ; str [i]]!='0'; i++)
if( isv(str[i]))
v[j++] = str[i[;
for ( int i = 0; str[i]! = '0' ; i++
if ( isv (str[i]))
str{i} = v [--j]
return str;
}
int main ()
{ string str = " Programming";
cout<<swapv(str);
return 0 ;
}
Answer:
Switch-case statements are a powerful tool for control in programming. In this article, Sreeram Sceenivasan goes over you can use a switch-case statement in Python.
Explanation:
Python doesn’t need a switch statement. You can do exactly the same thing with if/elif/else statements.
Answer:
Following are the program in the Python Programming Language.
#set variable for input year by user
y=int(input("Enter year: "))
#set variable and initialize to 0
flag=0
#check condition that year is divisible by 4
if(y%4==0):
#check that the year is divisible by 100
if(y%100==0):
#check that the year is divisible by 400
if(y%400 ==0):
#then initialized flag to 1
flag=1
else:
#otherwise remain 0
flag = 0
else:
flag = 1
else:
flag = 0
#for break line
print()
#check that if flag is equal to 1
if(flag==1):
print("29 days in February")
#otherwise else
else:
print("28 days in February")
<u>Output</u>:
Enter year: 2020
29 days in February
Explanation:
<u>Following are the description of the program</u>:
- Set variable 'y' in which we get integer value as year from the user.
- Set variable 'flag' and initialize that variable to 0.
- Then, we set if-else conditional statements to check that the variable 'y' is divisible by 4 then, we check that the variable 'y' is divisible by 100 and we also check that the following variable is divisible by 400.
- Finally, we set if-else conditional statement to check that the variable 'flag' is equal to 1 then print about the leap year, otherwise it print about the non-leap year.
