Answer:
// program in java.
import java.util.*;
// class definition
class Main
{
// main method of the class
public static void main (String[] args) throws java.lang.Exception
{
try{
// object to read input
Scanner scr=new Scanner(System.in);
System.out.print("Enter the String:");
// read string from user
String str=scr.nextLine();
System.out.print("Enter the character:");
// read character
char ch=scr.next().charAt(0);
// variable to count the occurrence of character
int char_count=0;
for(int i=0;i<str.length();i++)
{
// find the character i string
if(ch==str.charAt(i))
// increase the count
char_count++;
}
// print the count
System.out.println("count of "+ch+" in the String is:"+char_count);
}catch(Exception ex){
return;}
}
}
Explanation:
Read a string from user and assign it to variable "str".Then read a character to and assign it to variable "ch".Then Declare a variable "char_count" to count the occurrence of character in the string.Find the count of character in the string. Here upper case character is different than lower case.
Output:
Enter the String:Monday
Enter the character:n
count of n in the String is:1
Enter the String:Nobody
Enter the character:n
count of n in the String is:0
Answer:
#program in python.
#variables
slice_area=14.125
pi=3.14159
#read diameter
d=int(input("Enter diameter of pizza:"))
#area of pizza
area=pi*(d/2)*(d/2)
#number of slice
no_slice=int(area/slice_area)
#print slice
print("total silce are:",no_slice)
Explanation:
Declare and initialize a variable "slice_area" with 14.125 which is the area of a pizza slice.Initialize a variable "pi" with 3.14159.Then read the diameter of pizza.Find the area of pizza as "area=pi *d/2*d/2".Divide the total area with area of pizza slice.This will be the number of slice.
Output:
Enter diameter of pizza:20
total silce are: 22
