Question

for input matrix a , write a function to return the element in row 2 column 3 of that matrix

Answer 1

Since you have not mentioned language i'm doing this in python.

# A basic code for matrix input from user

R = int(input("Enter the number of rows:"))
C = int(input("Enter the number of columns:"))

# Initialize matrix
matrix = []
print("Enter the entries row wise:")

if(R!=0) and (C!=0):
# For user input
for i in range(R):       # A for loop for row entries
   a =[]
   for j in range(C):   # A for loop for column entries
       a.append(int(input()))
   matrix.append(a)

# For printing the matrix
for i in range(R):
   for j in range(C):
       print(matrix[i][j], end = " ")
   print()     
print("The element in 2nd row 3rd column is ",matrix[1][2])
