So, here is how to take input and show output to the user.
printf();
printf is a function that is used display desired output to the user.
printf is a function of <stdio.h> header file, yes, we include this file to include standard input output features, and printf and scanf are part of it.
Example:
printf(“Hello Bro!”);
Ouput:
Hello Bro!
Remember that if you want to show your desired sentence in printf command, you have to write it in ” “.
Their is a big reason why we write the sentence in ” “.
scanf();
As printf is used to show output, scanf is used to get input.
Example:
int a;printf(“Enter age :”);scanf(“%d”,&a);
Output:
Enter age19
Till now, just remember that scanf have two parts, one in ” “, and the other were we use variables, we will deeply understand this topic after you get to know what is a variable.
