Below is a program to reverse a string using pointer:#include <stdio.h> int main() { printf("\n\n\t\tStudytonight - Best place to learn\n\n\n"); char str[100]; char rev[100]; char *sptr = str; // sptr stores the base address of the str char *rptr = rev; // rptr ...

Then in the project, we will develop a recursion function which we will call later on in the code for reversing the strings. Declare a function with the return type “void” and name it “reverse.” The parameters of this function will be char type pointer string as “char*string.” In...
Here’s a solution in C: #include<string.h>#include<assert.h>#include<stdlib.h>voidreverse(char*s){intleft=0;intlen=0;for(;s[len]!='\0';len++);while(len>1){charleft_c=s[left];s[left]=s[left+len-1];s[left+len-1]=left_c;left++;len-=2;}}voidtest(char*input,char*out...

The left pointer begins pointing with the first character of the string and the right pointer points at the last character. In the while loop, we are making the left side of the array equal to the rightmost characters in the string, and the right side of the array equal to the leftmost...

If yes, then the return value (a pointer) of the function has the same value as the input parameter s. If not, then the function must dynamically allocate memory for the C-string that it will return. In any case, the main purpose of homework is to learn by doing things yourself. It...
