And to modify a string value, thestrcpy()function is useful again: Example struct myStructure { intmyNum; charmyLetter; charmyString[30]; }; intmain() { // Create a structure variable and assign values to it structmyStructure s1 = {13,'B',"Some text"}; ...
In C++, a structure is the same as a class except that its members are public by default. For information on managed classes and structs, see Classes and Structs. Using a Structure In C, you must explicitly use the struct keyword to declare a structure. In C++, this is unnecessary once...
