The contents of the character array are: "Student a Am I"; change the contents of the array to: "I am a student"

The contents of a character array are : "Student A Am I", Please change the contents of the array to "I am a student".

Requirements: Library functions cannot be used. Only a limited space can be opened (the number of spaces is independent of the length of the string).

The code is as follows:

#include  <stdio.h> #include  <stdlib.h> #include  <assert.h>void reverse_str (Char *left, char *right) {assert (left), assert (right);while  (left < right) {char tmp = *left;*left  = *right;*right = tmp;left++;right--;}} Int my_strlen (CONST&NBSP;CHAR&NBSP;*&NBSP;STR) {int count = 0;while  (*str++) {count++;} Return count;} Void reverse (char arr[])//(CAHR&NBSP;*STR) {char *pstart = arr;char *pend =  arr + my_strlen (arr) -1;char *pcur = null;if  (Arr == NULL)   ||   (arr[0] ==  ')) {return;} Reverse_str (pstart, pend);//reverse the entire character array while  (*arr) {pcur = arr;while  (*arr !=  '  && *arr !=  '   ') {arr++;} Pend = arr - 1;reverse_str (pcur, pend);if  (*arr ==  '   ') arr++;}} Int main (){char arr[] =  "Student a am i";//i ma a tneduts//i am a  studentreverse (arr);p rintf ("%s\n",  arr); System ("pause"); return 0;}
