GTU PPS Program - 18

18. Write a program to reverse a number.

#include<stdio.h>
#include<conio.h>
int main()
{
    int num,rev=0,i,j;
    printf("\nEnter number : ");
    scanf("%d",&num);
    while(num!=0)
    {
        i=num%10;
        rev=rev*10+i;
        num/=10;
    }
    printf("\nReverse is %d",rev);
    getch();
    return 0;
}

2). Write a program that solves the following equation and displays the value x and y: 1) 3.4x+50.2y=44.5 2) 2.1x+.55y=5.9 (Assume Cramer’s rule to solve equation ax+by=e x=ed-bf/ad-bc cx+dy=f y=af-ec/ad-bc ). Here we will create a general program and then add our equations as input import java.util.Scanner; class Program_02 { public static void main(String[] args) { Scanner input = new Scanner(System.in); System.out.println("Values of equation 1 :"); System.out.print("Enter value of a : "); double a = input.nextDouble(); System.out.print("Enter values of b : "); double b = input.nextDouble(); System.out.print("Enter value of e : "); double e = input.nextDouble(); System.out.println("Values of Equation 2 : "); System.out.print("Enter value of c : "); double c = input.nextDouble(); System.out.print("E...

5. Write a shell script which will accept a number and display first n prime numbers as output. Complete code of the program read -p "Enter the value of n (or range) " n echo "The prime numbers are: " m=2 while [ $m -le $n ] do i=2 flag=0 while [ $i -le `expr $m / 2` ] do if [ `expr $m % $i` -eq 0 ] then flag=1 break fi i=`expr $i + 1` done if [ $flag -eq 0 ] then echo $m fi m=`expr $m + 1` done Interpreting the prime.sh file and executing it in terminal tkanu025@hp:~/lab_solutions$ chmod +x prime.sh tkanu025@hp:~/lab_solutions$ ./prime.sh Output Previous Program Next Program gtu os lab manual, os GTU Practical, operating system Programs, Operating system shellscript programs, Gtu study material 3140705, OS 314070...

15). Write the bin2Dec (string binary String) method to convert a binary string into a decimal number. Implement the bin2Dec method to throw a NumberFormatException if the string is not a binary string. import java.util.Scanner; class Program_15 { public static int bin2Dec(String binString) throws NumberFormatException { int decimal = 0; int strLength = binString.length(); for (int i = 0; i < strLength; i++) { if (binString.charAt(i) < '0' || binString.charAt(i) > '1') { throw new NumberFormatException("Please Enter a Binary String"); } decimal += (binString.charAt(i) - '0') * Math.pow(2, strLength - i - 1); } return decimal; } public static void main(String[] args) { Scanner input = new Scanner(System.in); System.out.print("Enter Binary String : "); String str = input.nextLine(); try {...
