Learning outcome: assess student$$s ability to:

Create a $2$D array in a program.

Access data in a $2$D array.

Generate and use random numbers.

Activity description: sum of all ODD numbers of the value in each ROW of a $5-$by$-5$ matrix $(2$D array$).$

Create a program that will sum all ODD numbers in each ROW of a $2-$dimension array. The program will:

Set the size of an array as a global constant variable with value of $5.$

define function rand$\_$number$().$ Function rand$\_$number$()$ is used to randomly generate a value between $-20$ and $20$ and return the value as an integer.

Define function populate$\_$rand$\_$numbers$().$ Function populate$\_$rand$\_$numbers$()$ is used to populate the $5-$by$-5$ matrix. It means that each cell of the $5$ rows and $5$ columns will be populated with one random number. This random number is obtained by using function rand$\_$number$().$

define function print$\_$rand$\_$number$().$ Function print$\_$rand$\_$number$()$ is used to print the value in each cell of the $5-$by$-5$ array.

define function sum$\_$odd$\_$row$().$ Function sum$\_$odd$\_$row$()$ is used to sum all ODD numbers of the values in each ROW of a $5-$by$-5$ array.

Define function prompt$\_$sum$\_$odd$\_$row$().$ The function is used to print the result of the sums as:

Sum all odd numbers in row $1=\_\_\_\_$

Sum all odd numbers in row $2=\_\_\_\_$

Sum all odd numbers in row $3=\_\_\_\_$ solve thius c$++$ programthis
