Give precise and direct code.
Transcribed Image Text:Declare a C++ string object named myStr and
initialize with the string "EFC1103", then print it
using printf.
Given the following declaration of a string and an
integer, write a line of code to convert the string to
integer and add it to the integer below (iHundred).
string sHundred = "100";
int iHundred = 100;
The following C/C++ structure Matrix2x2 is to
a b
M =
c d
define a 2x2 matrix such as
The determinant of such matrix is det(M) = ad-bc.
Write 2 lines of declaration with initialization, to
4 7
M =
10 1
show how you create a matrix
and an integer detM = det(M).
struct Matrix2x2 {double a, b, c, d; };
