Fix buffer overflow issue by adjusting input buffer size and fgets usage

Description

This pull request addresses the issue of a segmentation fault occurring when a name longer than 80 characters is entered into the program. The fix involves increasing the buffer size for the name variable and correcting the usage of the fgets function to prevent buffer overflow.

Changes Made

• Increased the buffer size for the name variable from 64 to 128 characters.
• Corrected the fgets function to use sizeof(name) instead of sizeof(name) + 32.

Issue Reference

This pull request fixes issue #6.

Testing

• Manually tested the program by entering names of various lengths, including names longer than 80 characters, to ensure no segmentation fault occurs.
• Verified that the program correctly handles input and removes the trailing newline character.

Notes

• The changes are limited to the main.c file.
• The fix ensures that the program can safely handle longer input without causing a segmentation fault.
