- Guys whatever we do in our daily life is to benefit us .
- For example we keep the fruits in mixer to get juice .
- Here we getting a benefit of converting fruits to juice .
- Similarly, we are doing coding for some benefits .
- Similar to mixer we give some inputs to our code/program and get benefits through output .
- For example we written a code to multiply two numbers then for our given input we get output .If we given 8 and 7 as input we get output as 56 .
- Here cin will helps us to give input to program/code cout helps us to get the output .Lets study the cin and cout briefly with examples.
- Execution of cout in c++ with code and examples
- #include<bits/stdc++.h>
- using namespace std;
- int main()
- {
- int lecture_no = 3;
- cout<<"code with dare";
- cout<<endl;
- cout<<lecture_no;
- return 0;
- }
- OUTPUT :
- code with dare
- 3
- click here to know what is #inlude<bits/stdc++.h>
- In the above example code with dare is a sentence so it is kept between "" and lecture_no is a variable so it used directly .
- cout can be used two ways either we an print directly with sentence with quotes or can be printed via variables
- click here to know what are variables
- In above code endl used to shift to new line so in output 3 is printed in new line.
- We can print multiple answer at a time like shown below
- cout<<"code_with_dare"<<endl<<lecture_no;
- This above line also give same output
- Execution of cin in c++ with code and examples
- In the first code in line number 5 we initiated lecture_number with 3.Now we an ask user to provide the lecture number using cin.This is the beauty of coding.
- #include<bits/stdc++.h>
- using namespace std;
- int main()
- {
- int lecture_no ;
- cin>>lecture_no;
- cout<<lecture_no;
- return 0;
- }
- OUTPUT :
- depends upon user input .
- For the above code whenever we run the program it will ask user to give input and it will store in the variable name lecture_no .This can be done with line number 5
- Now ,as known line number 7 prints the number which is stored in lecture_no.
- Here i provide sample video which helps you in compiling code.Please see it
- 👀
- In the above video i compiled the two programs ,In second code it asked me for input and i given 5536262 as input it stored this number in lecture_no and printed 5536262as per line no 7
