You are given a two-dimensional array of 5 rows and 4 columns, formulated in a random way.

You are given a two-dimensional array of 5 rows and 4 columns, formulated in a random way. Find the sum of positive elements of 1 row and the number of negative elements of 3 columns.

program zz1;
const n = 5;
m = 4; // set the number of elements in the array
var i, j, k: integer; // set variables of integer type
b: array [1..n, 1..m] of integer;
begin
for i: = 1 to n do
for j: = 1 to m do // get numbers and write them into an array
b [i, j]: = random (101) -50;
for i: = 1 to n do // display the resulting array on the screen
begin
for j: = 1 to m do
write (b [i, j]: 4);
writeln;
end;
for j: = 1 to m do
if b [1, j]> 0 then k: = k + b [1, j];
writeln (‘the sum of positive elements of 1 line =’, k); // display the answer
k: = 0;
for i: = 1 to n do
if b [i, 3] <0 then k: = k + 1;
write (‘number of negative elements 3 columns =’, k); // display the answer
end.
