..il AT&T; 4:01 PM Ca 47% + Documents Homework 229 P4.1Write programs with loops that compute a. The sum of all even numbers between 2 and 100 (inclusive). b. The sum of all squares between 1 and 100 (inclusive). c. All powers of 2 from 20 up to 220. d. The sum of all odd numbers between a and b (inclusive), where a and b are inputs. e. The sum of all odd digits of an input. (For example, if the input is 32677, the sum would be 3 +7+7=17.) P4.3Write programs that read a line of input as a string and print a. Only the uppercase letters in the string. b. Every second letter of the string. c. The string, with all vowels replaced by an underscore. d. The number of digits in the string. e. The positions of all vowels in the string. P4.8Write a program that reads a word and prints each character of the word on a separate line. For example, if the user provides the input "Harry", the program prints 172 wordsExplanation / Answer
Answer:
As per the guidelines subparts of the 401 is solved, please repost others as an individual question.
a)
code:
#include<iostream>
using namespace std;
int main()
{
int num, sum = 0;
for(num=1; num<=100; num++)
{
if(num%2 == 0)
{
sum = sum + num;
}
}
cout<<"sum of even numbers between 1 to 100 is: "<<sum<<endl;
return 0;
}
b)
code:
#include<iostream>
#include<cmath>
using namespace std;
int main()
{
int num, sum = 0;
for(num=1; num<=100; num++)
{
sum = sum + pow(num, 2);
}
cout<<"sum of squares of numbers between 1 to 100 is: "<<sum<<endl;
return 0;
}
c)
code:
#include<iostream>
#include<cmath>
using namespace std;
int main()
{
double num, res = 0;
cout<<"Number"<<" "<<"Power"<<endl;
for(num=20; num<=200; num++)
{
res = pow(num, 2);
cout<<num<<" "<<res<<endl;
}
return 0;
}
d)
code:
#include<iostream>
using namespace std;
int main()
{
int a, b, sum = 0;
cout<<"Enter a: ";
cin>>a;
cout<<"Enter b: ";
cin>>b;
for(int i = a; i<= b; i++)
{
if(i %2 != 0)
{
sum = sum + i;
}
}
cout<<"Sum of odd numbers between "<<a<<" and "<< b<<" is "<<sum<<endl;
return 0;
}
