C doesn't provide jagged arrays but we can simulate them using an array of pointer to a string.if(typeof ez_ad_units != 'undefined'){ez_ad_units.push([[728,90],'overiq_com-medrectangle-3','ezslot_1',135,'0','0'])};__ez_fad_position('div-gpt-ad-overiq_com-medrectangle-3-0'); An array of pointers to strings is an array of character pointers where each pointer points to the first character of the string or the base address of the string. WebC is an imperative, procedural language in the ALGOL tradition. Arrays follow the normal C syntax of putting the brackets near the variable's identifier, so: int (*foo_ptr_array[2])( int ) declares a variable called foo_ptr_array which is an array of 2 function pointers. How to reverse an array using pointers in C programming. Then shift the array elements from this position to one position forward(towards right), and do this for all the other elements next to pos. So the above statement can also be written as: It is important to note that each element of the sports array is a string literal and since a string literal points to the base address of the first character, the base type of each element of the sports array is a pointer to char or (char*). He loves to learn new techs and write programming articles especially for beginners. Hence in order to sort the array using pointers, we need to access the elements of the array using (pointer + index) format. What is if __name__ == '__main__' in Python ? 1. In C programming, pointers and array shares a very close relationship. In this article, we will see how to insert an element in an array in C. In the last chapter, we have learned how we can use an array of strings or 2-D array of characters.
