Answer:
An application programming interface (API) is the code the CPU recognizes to perform a procedure in an application.
Explanation:
An application programming interface (API) is the code the CPU recognizes to perform a procedure in an application. API allows an application to communicate with another application, or an operating system, database, network, etc.
An Application Programming Interface (API) creates a consideration for a problem and specifies how clients should interact with software components that implement a solution to that problem.
More recently, API has been used to refer to a specific type of interface between a client and a server, which has been described as a “contract” between both - such that if the client makes a request in a specific format, it will always get a response in a specific format or initiate a defined action.This is a specialized form of API, defined as a Web API.
Answer:
The program to this question can be given as:
Program:
#include <stdio.h> //include header file.
int main() //defining main method
{
char i,j; //defining variable
for (i='a'; i<='e'; i++) //outer loop for column
{
for (j='a'; j<='e'; j++) //inner loop for row
{
printf("%c%c\n",i,j); //print value
}
}
return 0;
}
Output:
image.
Explanation:
- In the above C language program, firstly a header file is included. Then the main method is defined in this, a method contains a char variable that is "i and j". This variable is used in for loop, that is used to print the pattern.
- To print the following patter two for loop is used the outer loop is used for print columns and the inner loop prints row.
- In C language to print character, we use "%c" inside a loop print function is used, that prints characters.
