Answer:
Answered below
Explanation:
//Program is written in Python programming language
def charCnt( fileName, char){
if not fileName.exists( ):
return sys.exit(1)
else:
openFile = open("$fileName.txt", "r")
readFile = openFile.read( )
fileLength = len (readFile)
count = 0
for character in range(fileLength):
if readFile[character] == char:
count++
openFile.close( )
return count
}
Answer:
See explaination
Explanation:
MinMax.java
import java.util.*;
public class MinMax
{
static void MinMax(int[] arr)
{
int Min=arr[0]; // initializinf min and max with 1st value of array
int Max=arr[0];
for(int i=0;i<arr.length;i++) // iterating loop only once
{
if(arr[i]>Max) // checking max value
{
Max=arr[i];
}
if(arr[i]<Min) // checking min value
{
Min=arr[i];
}
}
System.out.println("Min Number is "+Min); //printing min value
System.out.println("Max Number is "+Max); //printing max value
}
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
System.out.print("Enter N value: "); // taking n value
int n=sc.nextInt();
int[] arr=new int[n];
System.out.println("Enter N elements:"); // taking n elements into array
for(int i=0;i<n;i++)
{
arr[i]=sc.nextInt(); // each element into the array
}
MinMax(arr); // calling MinMax() method.
}
}
Answer: a sentinel value
Explanation:
a sentinel value is a value that is used as a condition to end the program. notice that it says "enter -1 to end"
