Final answer:
To assign only the number 750 to the strSalary variable from a string that includes a dollar sign ('$750'), string manipulation functions such as Substring or TrimStart can be used to remove the dollar sign and extract the numeric part.
Step-by-step explanation:
The statement that will assign only the number 750 to the strsalary variable is:
strsalary = txtsalary[1:]; string manipulation functions such as Substring or TrimStart can be used to remove the dollar sign and extract the numeric part.
This statement uses string slicing to extract a substring starting from the second character (index 1) until the end of the string. This will exclude the dollar sign and assign only the number 750 to the strsalary variable.
