Change c++ into c

Question

Can someone change this code in c++ into c code?
// CPP program to print diagonal star patterns
#include <iostream>
using namespace std;

void pattern(int n)
{
    // Loop denoting rows

    for (int i = 0; i < n; i++) {

        // Loop denoting columns

        for (int j = 0; j < n; j++) {

            // Checking boundary conditions and main

            // diagonal and secondary diagonal conditions

            if (i == 0 || j == 0 || i == j || i == n - 1 

                            || j == n - 1 || i + j == n - 1)

                cout << "*";

            else

                cout << " ";

        }

        cout << endl;

    }
}

// Driver code
int main()
{
    // n denotes size which should be odd

    int n = 7;

    // Function calling

    pattern(n);

    return 0;
}

Answer 1

Saba looks like code is copied from internet as its contain stray especial character which shows when you copied from any source or ide to sololearn.

For converting into c all are good by syntax you just need to add printf instead of cout
// CPP program to print diagonal star patterns
#include <stdio.h>
void pattern(int n)
{// Loop denoting rows
for (int i = 0; i < n; i++) {
// Loop denoting columns
for (int j = 0; j < n; j++) {
// Checking boundary conditions and main
// diagonal and secondary diagonal conditions
if (i == 0 || j == 0 || i == j || i == n - 1 || j == n - 1 || i + j == n - 1)
printf("*");
else
printf(" ");
}
printf("\n");
}
}
// Driver code
int main()
{
// n denotes size which should be odd
int n = 7;
// Function calling
pattern(n);
return 0;
}

Answer 2

Don't give such questions
1.instead of iostream use stdio.h
2.erase the 2nd line
3.instead of cout use printf

Answer 3

Declare int i,j at start of function patterns

Answer 4

Then change n in patterns to x

Answer 5

Replace the header with-
#include<stdio.h> and remove
using namespace std;
Also replace all your cout with-
printf("*");
printf (" ");
printf("\n");

This is C.

Answer 6

i replaced them already but it just errored

Answer 7

it says error:unpaired curly brackets

Answer 8

i did

Answer 9

Simple
Change Header file
And instead of cout .printf is used
