14. isdigit() Returns true if the string contains only digits and false otherwise. 15. islower() Returns true if the string has at least 1 cased character and all cased characters are in lowercase and false otherwise 16. istitle() Returns true if the string is properly "titlecased" and ...
Consider the following C-like program: int fun(int *i) { *i +=5; return 4; } void main() { int x = 3; x = x + fun(&x); } What is the value of "x" after the assignment statement in main, assuming a) Suppose a, b, and sum are int variables and c i...
Consider the assignment statement: result = isdigit('$') What is the value for result? ASSIGNMENT (EmployeeNumber, ProjectNumber, ProjectName, HoursWorked) Assume that ProjectNumber determines ProjectName and explain why this relation is not normalized. Demonstrate an insertion anomal ...
aTypically, the routines in this library conform to the ANSI C Standard. However, some functions differ slightly in order to take advantage of the features found in the 8051 architecture. For example, the function isdigit returns a bit value as opposed to an int. Where possible, function retur...
