Mandatory, Warning and Informatory Road Signs and Meaning in Urdu

In this post, we will see all kinds of road signs India and their meaning in Urdu language. The traffic signs can be divided into three categories:

• Mandatory or Regulatory Road Signs  (لازمی یا ریگولیٹری روڈکے نشان)
• Cautionary or Warning Road Signs (انتباہ روڈکے نشان)
• Informatory Road Signs

Mandatory Road Signs

The following video shows almost all mandatory road signs used in India. The meaning of each traffic sign in Urdu is also given in the video.

Cautionary or Warning Road Signs

The following video shows almost all warning road signs or Cautionary road signs used in India. This kind of traffic signs give warnings to avoid accidents. The meaning of each warning traffic sign in Urdu is also given in the video.

Informatory Road Signs

As the name suggests, the informatory road signs give information about petrol pump, hospital, restaurant, public telephone, resting place, first aid post, parking places etc. The meaning of each informatory traffic sign is also given in the video.

How to make tables using HTML code

In HTML (Hyper Text markup Language), <table> tag is used to create tables. Table is basically meant to represent data in tabular form. But people also use tables to design webpages, especially when they want to divide the web pages into some equal blocks. Now we will start with the basics of table tag. The table starts with a <table> tag and ends with the HTML tag </table>. Whatever comes in between <table> and </table> is either the data in the table or further HTML codes to design the table. These two tags help only to inform the starting and ending of the table.

Intel 8085 Microprocessor Instructions - Hex codes and Mnemonics

In this post, we will see the 8085 Microprocessor instructions and corresponding hex codes. This table is useful to hand assemble the  8085 program. In many universities, 8085 programming is included for practicals under computer science and engineering courses. Each mnemonic has its own hex codes. An assembler is a program which converts the code written in mnemonics into hexadecimal codes. The monitor program (part of microprocessor kit) translates the hex codes to corresponding actions to be performed by CPU.

Conditional Operator in C and C++

Conditional Operator is an operator which is substitutive for if-else statements. It is a ternary operator (operator which operates on 3 operands). It is often called ?: operator. The operands are expression1, expression2 and expression3. The syntax is as follows:

expression1 ? expression2 : expression3

The expression expression1  will be evaluated always. Execution of expression2 and expression3 depends on the outcome of expression1. expression1 is checked whether true or not. It is considered like a boolean variable. The outcome of an expression is true if it has a non zero value. If its value is zero, the outcome of expression is false. If the expression1 is true, then expression2 is evaluated. If the expression1 is false, then expression3 is evaluated. Consider the following example:

Linear Search in C and C++ Languages

Linear search simply means 'looking for an element in the whole array from one end to the other'. The searched element is compared with the first element of array first, then with the second, then with the third, so on upto the end of the array. This is time consuming when the array is pretty enough. The time complexity is highest.The C and C++ programs for linear search is given below.

C Program:

#include<stdio.h>

void main()
{

C and C++ Programs to Check Whether a Number is Strong Number or Not

This post contains C and C++ program to check whether a given number is Strong number or not. A strong number is a number for which the sum of factorials of its digits is equal to the number itself. The first one is C program to check whether the input number is a strong number or not. An example is 145. 1!+4!+5!=1+24+120=145 Therefore 145 is a strong number.

C Program:

#include<stdio.h>
long int factorial(int n)

String Comparison in C and C++ Languages and Working of strcmp function

In both C and C++ programming languages, an inbuilt function strcmp() is used to compare two strings. This function is defined in string.h header file. So, to use this function, you have to include the header file string.h in the program. Most of the people ( i mean beginners) have a wrong idea about the working of the this function. I also had made some false assumptions. This function takes two strings as arguments. And it compares the two strings using the ASCII equivalent of each character. Some of the false ideas about this function are:

• The function returns 1 when the strings are equal and 0 when they are not equal
• The function returns 1 when they are not equal
• The function returns 1 when the first string is greater than the second and returns -1 when the first one is less than the second one

C Program for Subtraction Without Using Minus Sign

The following is a program to subtract a number from another without using minus symbol. Instead of doing a normal subtract operation, the two's complement of the subtrahend is added to the minuend. (In 3-4, 3 is minuend and 4 is subtrahend.) In other words, the 1's complement and 1 is added to minuend.

#include<stdio.h>
void main()
{
int a,b,sum;
printf("Enter any two integers: ");

scanf("%d%d",&a,&b);
sum = a + ~b + 1;
printf("Difference of two integers: %d",sum);
}

C and C++ Programs to Find Sum of Digits of a Given Number

The following are C and C++ programs to find sum of digits of any given integer.

C Program

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