hello dear students let us see how to pass array to a function and further understand relation of array and pointer now check that in this particular slide i have written one program in which the main is declaring an array of phi elements and also we are initializing those values of the elements to one two three four five so we can imagine that in ...

Key Insights

• 👻 The name of an array in C is considered as the address of the array, allowing it to be passed as a pointer to a function.
• 🧭 When passing an array to a function, only the start address is passed, not the entire list of values.
• ♿ The array parameter in the function declaration is converted into a pointer, giving access to the elements of the array using pointer notation.
• 🎅 Arrays in C can be accessed using either array notation or pointer notation.
• 🎅 The size of the array can be specified in the function declaration or left empty, as C can determine the size based on the number of elements passed.
• 👻 The ability to pass arrays as pointers allows for more efficient and faster processing of data.
• 🧭 A function can modify the values of an array passed to it by using pointer notation.

Summary & Key Takeaways

• Arrays in C are sequentially stored in memory, with indexing starting from 0 and a base address where the array starts.

• When passing an array to a function, only the start address of the array (the array's name) is passed, rather than passing the entire list of values.

• The array parameter in the function declaration is converted into a pointer, allowing access to the elements of the array using pointer notation.
