Make Your Own Header File ?

Step1 : Type this Code 

1 2 3 4

int add(int a,int b) { return(a+b); }

• In this Code write only function definition as you write in General C Program

Step 2 : Save Code

• Save Above Code with [.h ] Extension .
• Let name of our header file be myhead [ myhead.h ]
• Compile Code if required.

Step 3 : Write Main Program

1 2 3 4 5 6 7 8

#include #include"myhead.h" void main() {    int num1 = 10, num2 = 10, num3;    num3 = add(num1, num2);    printf("Addition of Two numbers : %d", num3); }

1. Include Our New Header File .
2. Instead of writing < myhead.h> use this terminology “myhead.h”
3. All the Functions defined in the myhead.h header file are now ready for use .
4. Directly  call function add(); [ Provide proper parameter and take care of return type ]

Note

1. While running your program precaution to be taken : Both files [ myhead.h and sample.c ] should be in same folder.

What Is the Difference between .conatiner  and .container-fluid in bootstrap???

Quick version: .container has one fixed width for each screen size in bootstrap (xs,sm,md,lg); .container-fluid expands to fill the available width.

---

The difference between container and container-fluid comes from these lines of CSS:

@media (min-width: 568px) {
  .container {
    width: 550px;
  }
}
@media (min-width: 992px) {
  .container {
    width: 970px;
  }
}
@media (min-width: 1200px) {
  .container {
    width: 1170px;
  }
}

Depending on the width of the viewport that the webpage is being viewed on, the container class gives its div a specific fixed width. These lines don't exist in any form for container-fluid, so its width changes every time the viewport width changes.

So for example, say your browser window is 1000px wide. As it's greater than the min-width of 992px, your .container element will have a width of 970px. You then slowly widen your browser window. The width of your .container won't change until you get to 1200px, at which it will jump to 1170px wide and stay that way for any larger browser widths.

Your .container-fluid element, on the other hand, will constantly resize as you make even the smallest changes to your browser width.

Multiplication Using Multiplication

(Urdhva Tiryagbhyaam)

Consider the following example :

            37 * 33

Step 1 : Write it as follows

                    37

                    33

Step 2 : Multiply the left most column vertically and  write it below.

             Multiply 3 * 3 to get 9

                    37

                    33

                    9

Step 3 : Next multiply diagonally and add

            i.e. (3*3) + (3*7) = 9 + 21 = 30

Since 30 is a 2 digit number put the last digit (here '0' ) next to 9 and the other digits (here '3' ) below 9

                    37

                    33

                    90

                    3

Step 4 :  Now multiply the RHS column and put it below and total to get the Answer.

                    37

                    33

                    901

                    32 

                   1221

  Hence 1221 is the Answer
