C lan If statement issue about ds problem - c

Question

This below is my ds hw code.
#include <stdio.h>
typedef struct
{
int row;
int col;
int val;
}term;
void CreateTriplet(term t[],int a[][10],int m, int n)
{
int i, j, k = 0;
t[0].row = m;
t[0].col = n;
for (i = 0; i < m; i++)
{
for (j = 0; j < n; j ++)
{
if(a[i][j] == 0)
continue;
k++;
t[k].row = i;
t[k].col = j;
t[k].val = a[i][j];
}
}
t[0].val = k;
}
void printTriplet(term t[], int k)
{
int i;
for(i = 0 ; i < k ; i++)
{
printf("%d\t", t[i].row);
printf("%d\t", t[i].col);
printf("%d\n", t[i].val);
}
}
void findTranspose(term t1[], term t2[])
{
int i, j, k;
t2[0].row = t1[0].col;
t2[0].col = t1[0].row;
t2[0].val = t1[0].val;
k = 1;
for (i = 0; i < t1[0].col; i++)
{
for (j = 1; j <=t1[0].val; j++)
{
if (t1[j].col == i)
{
t2[k].row = t1[j].col;
t2[k].col = t1[j].row;
t2[k].val = t1[j].val;
k++;
}
}
}
}
int main()
{
int a[10][10], i, j, m, n, zero=0, nonzero;
term t1[101], t2[102];
scanf("%d %d", &m, &n);
for(i = 0; i < m ;i++)
{
for(j= 0; j < n ;j++)
{
scanf("%d]\n", &a[i][j]);
if(a[i][j]==0)
zero++;
}
}
if (i*j != i*i && j*j) /* I have no idea how to modify this section for the output*/
{
printf("Input matrix has wrong size. Please input again. \n");
}
else
{
nonzero = m * n - zero;
printf("Sparse matrix by triplet form:\n");
CreateTriplet(t1, a, m, n);
printTriplet(t1, nonzero+1);
findTranspose(t1, t2);
printf("Transpose of the sparse matrix:\n");
printTriplet(t2, nonzero+1);
}
return 0;
}
The main problem is in the section (if statement.)
When I was writing the if conditional, the input size was 6 * 6. Also, the elements in the matrix are not 6 * 6. My idea is to let the condition determine row * col != input elements. I don't know how to modify the if statement. Can someone help me?
**Input**
55
15 0 0 22 0
0 0 3 0 0
0 0 0 -6 0
0 0 0 0 7
91 0 0 0 0
**Output**
Sparse matrix by triplet form:
5 5 6
0 0 15
0 3 22
1 2 3
2 3 -6
3 4 7
4 0 91
Transpose of the sparse matrix:
5 5 6
0 0 15
0 4 91
2 1 3
3 0 22
3 2 -6
4 3 7
**Input**
66
15 0 0 22 0 -15 100
0 11 3 0 0 0
0 0 0 -6 0 0
0 0 0 0 0 0
91 0 0 0 0 0
0 0 28 0 0 0
1 0 0 0 0 0
**Output**
Input matrix has wrong size. Please input again.
