writing the c code mesafe$\_$hesapla$($arg$$manlar$)$:

This function takes four arguments: the x and y coordinates of the first point, and the x and y coordinates of the second point.

It calculates the Euclidean distance between the two points using the formula:distance$=($x$2$x$1)2+($y$2$y$1)2$

The function returns the calculated distance.

en$\_$kisa$\_$mesafe$($arg$$manlar$)$:

This function takes a $2$D array noktalar$[][]$ as an argument.

Inside the function, it finds the two closest points and prints their indices $($numbers$)$ as shown in the sample output.

No need to return any value from this function. $($Note: When calculating distances between points, this function should call the mesafe$\_$hesapla$()$ function.$)$

Main function:

Ask the user for a seed number $($integer$)$ to generate random coordinates for the points.

Create an array noktalar$[$nokta$\_$sayisi$][2]$ to store the coordinates of the points $($where nokta$\_$sayisi $=5).$

Generate random x and y coordinates for each point within the range $[0,99].$

Finally, call the en$\_$kisa$\_$mesafe$()$ function with appropriate arguments.
