This program has to be coded in C++, you can also do the 3 problems easily by using the following source code.
int r, // row (or line) counter
c; // column counter
// design 1
// for (r=1... takes care of displaying 3 rows
for (r=1; r
{
// one iteration of the body of this loop displays row number r.
// In other words, " when r is 1, row 1 is displayed; // when r is 2, row 2 is displayed; ..."
// for (c=1... takes care of displaying the 5 columns in row
// number r
for (c=1; c

Problem 8 (10 points) Modify (save into a different file) your source code file so that it displays on the screen a design similar to design 7, except that the design is a "slightly different triangle." For example, if the user wants the size of the design to be 5 and the selected symbol to be@', the program will display the following design Hint The design consists of the number of rows specified by 'size Row 1 consists of 4 leading blanks, followed by 1 selected symbol Row 2 consists of 3 leading blanks, followed by 2 selected symbols. Row 3 consists of 2 leading blanks, followed by 3 selected symbols. Row 4. Can you detect the "pattern" in each row? Problem 9 (10 points) Modify (save into a different file) your source code file so that it displays on the screen a design similar to design 8, except that the design is a bit more complex. For example, if the user wants the size of the design to be 5 and the selected symbol to be'#', the program will display the following design Hint: To display this design, first display its top half, and then its bottom half. Validate the value of size read from the user to be between 1 and 10, inclusive
