An assertion is a statement which is used to declare positively that a fact must be true when that line of code is reached.Assertions are useful for obtaining the expected conditions which are met.Simple AssertionSimple assertion can be implemented by using assert (expression) method, which is present in assert.h header file.The syntax for simple assertion is as follows −assert(expression)In simple assertion, When the condition passed to an assertion which is a true, then, there is no action.The behaviour on false statements depends completely on compiler flags.When assertions are enabled, a false input causes a program to halt.When assertions are disabled, ...

ProblemWrite a program to find the sum of perfect square elements in an array by using pointers.Given a number of elements in array as input and the sum of all the perfect square of those elements present in the array is output.SolutionFor example, Input= 1, 2, 3, 4, 5, 9, 10, 11, 16 The perfect squares are 1, 4, 9, 16. Sum = 1 + 4 + 9 +16 = 30 Output: 30AlgorithmRefer an algorithm given below to find the sum of perfect square elements in an array by using pointers. Step 1 − Read number of elements in array at ...

For swapping two strings from one location to another location, we use strcpy() function.An array of characters (or) collection of characters is called a string.DeclarationFollowing is the declaration for an array −char stringname [size];For example, char string[50]; string of length 50 characters.InitializationUsing single character constantchar string[10] = { ‘H’, ‘e’, ‘l’, ‘l’, ‘o’ ,‘\0’}Using string constantschar string[10] = "Hello":;AccessingThere is a control string "%s" used for accessing the string till it encounters ‘\0’strcpy ( )This function is used for copying source string into destination string.The length of the destination string is greater than or equal to the source string.The syntax ...
