Question
Write a program that reads a 5 x 5 two-dimensional array of integers and then prints the row sums and the column sums: Row Totals: Column Totals: You may either initialize this array within the program or have the user type in the values at run time. This is as far as i've gotten. thank you for your help #include #include int main() { #define NUMROWS 5 #define NUMCOLS 5 int val[NUMROWS][NUMCOLS] = { 8, 4, 5, 6, 3, 10, 15, 7, 9, 1, 2, 7, 25, 34, 66, 6, 44, 12, 8, 9, 9, 5, 4, 2, 7 }; int i, j; sunrow0 = val[0][0] + val[0][1] + val[0][2] + val[0][3] + val[0][4]; sunrow1 = val[1][0] + val[1][1] + val[1][2] + val[1][3] + val[1][4]; sunrow2 = val[2][0] + val[2][1] + val[2][2] + val[2][3] + val[2][4]; sunrow3 = val[3][0] + val[3][1] + val[3][2] + val[3][3] + val[3][4]; sunrow4 = val[4][0] + val[4][1] + val[4][2] + val[4][3] + val[4][4]; sumcol0 = val[0][0] + val[1][0] + val[2][0] + val[3][0] + val[4][0]; sumcol1 = val[0][1] + val[1][1] + val[2][1] + val[3][1] + val[4][1]; sumcol2 = val[0][2] + val[1][2] + val[2][2] + val[3][2] + val[4][2]; sumcol3 = val[0][3] + val[1][3] + val[2][3] + val[3][3] + val[4][3]; sumcol4 = val[0][4] + val[1][4] + val[2][4] + val[3][4] + val[4][4]; Rtotal= (sumrow0 +sumrow1 +sumrow2 + sumrow3 + sumrow4); Ctotal = (sumcol0 + sumcol1 + sumcol2 + sumcol3+ sumcol4); printf(" ROW totals = %d", Rtotal); printf(" COLUMN totals = %d", Ctotal); getchar(); return 0; }
