A method and a system have been disclosed for detecting one or more memory leaks in a program. The method includes receiving the program code. After receiving the program, the program is tokenized automatically in a predefined format. The predefined format may correspond to a format which is up-loadable to a database. Thereafter, the tokenized program code is analyzed to determine control flows in the program by using a memory leak pattern. The memory leak pattern is an incorrect control flow between the combination of memory allocation and memory de-allocation functions. After analyzing the tokenized program, the memory leaks are identified based on the determined control flows in the program. The memory leaks are identified during the development phase of the program code. Subsequently, the memory leaks are fixed by a programmer.
