In this task, you will perform matrix multiplication. First, the user will input the size for each
matrix. You have to print the result of the operation if the operation is possible.

Expert Solution
Step 1
First some basics of matrix multiplication are if two matrices A and B of sizes a,b and x,y are to be mutiplied then bdhoul be equal to x and the mutipled matrix will be of order a*y
Going through the code I will fill the "??" blanks by writing the code below,please refer:
line 8 : if(m!=n_ && m!=0 && n!=0 && m_!=0 && n_!=0)
{
printf("(n,m),(n_,m_)->(n,m_), stmt, m,n_)
line 12 :
else {
float A[n][m],float B[n_],[m_];
line 16 ,17 for(int i=0;i<n;i++) , for(int j=0;j<m;j++)//for array A
line 23,24 for(int i=0;i<n_;i++) , for(int j=0;j<m_;j++)// for array B
