What is Jagged Array in C?
A Jagged array is an array of arrays. You can initialize a jagged array as − int[][] scores = new int[2][]{new int[]{92,93,94},new int[]{85,66,87,88}}; Where, scores is an array of two arrays of integers - scores[0] is an array of 3 integers and scores[1] is an array of 4 integers.
How an array is created in c?
For any type T, the type T[n] is an array of n Ts. If n is known at compile time, the array is fixed-length and the compiler will allocate n * sizeof(T) bytes to the array name. If n is not known at compile time, the array is variable-length and the programmer must manually request n * sizeof(T) bytes from the system at runtime, storing the start address in a pointer. The programmer must keep track of the stored address at all times and must release the memory as soon as it is no longer required.
Is it necessary to initialize the const variable in c?
A constant variable cannot have its value changed at program run time.
What is the lowest subscript of an array in c plus plus?
The lowest subscript of an array in C, or C++ is 0.
Missing semicolon in c program is a compile time error?
It's a syntax error, which is detected during compilation, yes.

Array in c plus plus must be defined at compil time?
No. Arrays can be defined at runtime, just as they can in C. It's just that it's generally more convenient to use vectors instead of dynamic arrays at runtime, thus arrays are generally used statically, at compile time.

A constant variable cannot have its value changed at program run time.
Is C plus plus preprocessor software?
Sometimes, it is. Some implementations compile C++ code into C code, and then compile the C code.
At what time the memory is allocated for variable in c and c?
Static memory allocation occurs at compile time where as dynamic memory allocation occurs at run time.
Can you give a sentence with the word compile?
I had to compile a list of all the people who had seen the accident. Take these reports and compile a history starting with the oldest dates first. The doctor asked me to compile my medical history.
What is the array of string in c?
A string in C is stored in a 1 dimension array so an array of strings is simply a two dimension array.
How do you compile c in textpad?
Not possible.
How size-of variable is used in c?
The Sizeof () operator only works at compile time and doesn't evaluate anything at run time.
What is the lowest subscript of an array in c plus plus?
The lowest subscript of an array in C, or C++ is 0.
Why array bound checks are not implemented by C plus plus compilers?
Array bounds checks are implemented in C++ just as they are in C. Static arrays are always bounds-checked at compile time but dynamic arrays must be bounds-checked at runtime, placing the onus upon the programmer to ensure all bounds are within range. Often, dynamic array bounds checks are completely unnecessary and would simply add a processing overhead that would only result in inefficient code, thus it is not implemented by default at runtime. The programmer is therefore free to use bounds checks only when it is absolutely necessary.
