Write a c-program to evaluate and print the truth table for (P ∧ Q) ∨ R.

Answer:


Step 1

Program:

Programs are used to interact with the computer system. The main objective of the program is problem-solving and providing interaction. Even the complex problems are solved using the programs and several tasks are performed based on the instructions given to the program.

A program is a code, that contains the instructions to do the task. The instructions are provided by the programmer using the programming languages such as Java, C, C++, etc. These programming languages read the input from various devices, processes it, and return the output.

#include<stdio.h>
#include<conio.h>

void main()
{
    
int p,q,r;
printf("P\tQ\tR\t(P∧Q)\t(P∧Q)VR");

for(p=0;p<=1;++p)
{
    for(q=0;q<=1;++q)
    {
        for(r=0;r<=1;++r)
        {
           printf("\n%d\t%d\t%d\t%d\t%d",p,q,r,(p&&q),(p&&q)||r);
        }

A palindrome is a number or a text phrase that reads the same backwards as forwards. For example, each of the following five-digit integers is a palindrome: 12321, 55555, 45554 and 11611. Write a C++ program that reads in a five-digit integer and determines whether it is a palindrome .

Question: A palindrome is a number or a text phrase that reads the same backwards as forwards. For example, each of the following five-digit integers is a palindrome: 12321, 55555, 45554 and 11611. Write a C++ program that reads in a five-digit integer and determines whether it is a palindrome . Answer: Step 1 PROGRAMING CODE:   #include <stdio.h> int main() {   int n, a, b, c, d, e;   int digit = 0;   printf( "Enter one 5 digit number: \n" );   scanf( "%d", &n );   a = n / 10000;   b = n / 1000 % 10;   c = n / 100 % 10;   d = n / 10 % 10;   e = n % 10;   if ( a == e && b == d ) {     printf( "Palindrome!\n" );   }   if ( a != e || b != d ) {     printf( "Not a palindrome.. :(\n" );   }   return 0; } PROGRAM SCREENSHOT: Step 2

QUESTION 6 (a) The bar shown in Figure Q2(a) is subjected to tensile load of 150 Kn. If the stress in the middle portions is limited to 160 N/mm², determine the diameter of the middle portion. Find also the length of the middle portion if the total elongation of the bar is to be 0.25 mm. E E = 2.0 + 105N/mm². (12 marks) 150 KN 10 cm DIA 10 cm DIA 150 KN 45 cm Figure Q6(a) (b) A brass bar, having cross-section area of 900 mm², is subjected to axial forces as shown in Figure Q2(b), in which AB = 0.6 m, BC = 0.8 m, and CD = 1.0 m. Find the total elongation of the bar. E = 1.0 + 105N/mm2 . (8 marks) Page 4 of 5 B D 40 KN 70 KN 20 KN 10 KN Figure Q6(b) (TOTAL = 20 MARKS)
