    C Pattern

    Uploaded by

    chakrabortyanjishnu9332
    The document contains C++ code snippets to print various patterns: a diamond pattern, pyramid pattern, hourglass pattern, inverted pyramid, Floyd's triangle, and Pascal's triangle. For each pattern type, the code uses loops and conditional statements to control the number and position of output characters ("*", spaces, numbers) on each line based on the pattern size and current row/column. It demonstrates using C++ features like functions, loops, conditionals, arrays to programmatically generate common numeric and geometric patterns.
