COBOL can handle variable-length files by using OCCURS DEPENDING ON clause to dynamically allocate memory based on the file size.

• COBOL uses OCCURS DEPENDING ON clause to handle variable-length files.

• The OCCURS DEPENDING ON clause allows for dynamic allocation of memory based on the file size.

• Example: 01 EMPLOYEE-RECORD. 05 EMPLOYEE-ID PIC X(5). 05 EMPLOYEE-NAME PIC X(20). 05 EMPLOYEE-SALARY PIC 9(6)V99 OCCURS DEPENDING ON NUM-EMPLOYEES.

CNN is used for image recognition while MLP is used for general classification tasks.

• CNN uses convolutional layers to extract features from images while MLP uses fully connected layers.

• CNN is better suited for tasks that require spatial understanding like object detection while MLP is better for tabular data.

• CNN has fewer parameters than MLP due to weight sharing in convolutional layers.

• CNN can handle input of varying sizes while MLP requires fixed input size.
