The number n^k is entered, I need to output the value in a character array-string

I have no idea how to write the code

Your problem does not seem well specified. You are not describing the problem or the limits in detail.

Regardless, here is some simple code to hopefully get you started.

#include <stdio.h>
#include <math.h>

int main(void) {
    int n;
    printf("Enter N:\n");
    scanf("%d", &n);
    
    int k;
    printf("Enter K:\n");
    scanf("%d", &k);
    
    int result = pow(n,k);
    char text[100];
    sprintf(text, "%d", result);
    
    printf("The Answer is %s\n", text);

    return 0;
}

Implement your own pow that would work with big numbers.

int main()
{
    int n, k;
    scanf("%d%d", &n, &k);
    char* s = (char*)malloc(1000000);
    int i, j, len, temp, carry;
    s[0] = '1';
    len = 1;
    for (i = 1; i <= k; i  )
    {
        carry = 0;
        for (j = 0; j < len; j  )
        {
            temp = (s[j] - '0') * n   carry;
            s[j] = temp % 10   '0';
            carry = temp / 10;
        }
        while (carry > 0)
        {
            s[len] = carry % 10   '0';
            carry /= 10;
            len  ;
        }
    }
    for (i = len - 1; i >= 0; i--)
        printf("%c", s[i]);
    return 0;
}
