Question

Use C:

3. In function main, declare a two-dimensional integer array with 5 rows and 4 columns. Call the following functions from function main. Call a function createArray to seed the random number generator and to fill the two-dimensional array with random integers between -20 and +20. Parameters for this function should be the array and the number of rows and columns). Call a function signs to count the number of positive values, number of negative values and number of zeros. Parameters are the array, number of rows, number of columns, and pointers to the number of positives, number of negatives, and number of zeros Call a function printResults to print the array and the number of positives, negatives, and zeros. There are six parameters, including the number of rows and columns, none of which needs to be a pointer

Note: Could you plz go this code and let me know if u need any changes in this.Thank You
