Computer Programming with C

10.1 INTRODUCTION

It is dicult to prepare and maintain a large-sized program. Moreover, the identication of the ow

of data is hard to understand. e best way to prepare a programming application is to divide the big-

ger program into small pieces or modules and the same modules can be repeatedly called from the

main() function as and when required. ese small modules or subprograms are easily manageable.

is method is called the divide and conquer method. In C, such small modules are called functions.

Figure 10.1 describes the method of developing a program.
