A computer program works the same way a child learns to carry out complex mathematical sums from kindergarten to intermediate classes. By acknowledging the process, we can easily understand the concept using which a computer program can be written. Arranging numbers in ascending or descending order are what a child learns in the starting years […]
FORTRAN programs become very lengthy while solving real engineering problems. To deal with such lengthy codes, the sequences of codes are identified that perform the same operation on different data. Then the user defines a subprogram that performs the above function. This subprogram is invoked within the main program whenever required. Subprograms are of two […]
