Error or exception is something that refers to the interruption of code execution due to which the expected outcome could not be attained to the end-user.On the basis of the event when an error is generated or identified we can classify them as Compile time error and runtime error.The following are the important differences between Compile Time Errors and Runtime Errors.Sr. No.KeyCompile Time ErrorsRuntime Errors1ReferenceCompile-time errors are generally referred to the error corresponding to syntax or semantics.Runtime errors on the other hand refer to the error encountered during the execution of code at runtime.2DetectionCompile-time errors get detected by compiler at ...

C programming Language C is a general-purpose, high-level language that was originally developed by Dennis M. Ritchie to develop the UNIX operating system at Bell Labs. C was originally first implemented on the DEC PDP-11 computer in 1972. In 1978, Brian Kernighan and Dennis Ritchie produced the first publicly available description of C, now known as the K&R standard. The UNIX operating system, the C compiler, and essentially all UNIX application programs have been written in C. C has now become a widely used professional language for various reasons − Easy to learn Structured language It produces efficient programs ... Read More

C# provides two methods to link value type to reference type and vice e Versa. These two methods for linking are named boxing and unboxing where Boxing is used for the conversion of the value type to an object type while Unboxing refers to the conversion of the object type to the value type.The following are the important differences between Boxing and Unboxing.Sr. No.KeyBoxingUnboxing1ImplementationBoxing made object type referred to as the value type.Unboxing basically processes the retrieving value from the boxed object.2StorageIn the case of boxing, the value stored on the stack is copied to the object stored on heap ...

Given an array of nxn size, the program must print the elements of an array in a snake pattern starting from the last column that means from arr[0][n]th element without doing any changes to their original locations.ExampleInput: arr[]= 100 99 98 97    93 94 95 96    92 91 90 89    85 86 87 88 Output: 97 98 99 100 96 95 94 93 92 91 90 89 88 87 86 85AlgorithmSTART Step 1 -> declare initial variable as int n to 5, i and j Step 2 -> declare array of 2-D matrix with elements Step 3 -> Loop For i=0 and i= 0; j--)             printf("%d ", arr[i][j]);       }    return 0; }Outputif we run the above program then it will generate the following output50 40 30 20 10 60 70 80 90 100 150 140 130 120 110 160 170 180 190 200 250 240 230 220 210
