Answer:
void printBackwards(char s[])
{
 int n=strlen(s)-1;//finding the last index of the string..
 for(int i=n;i>=0;i--)//loop to print the string backwards..
 {
 printf("%c",s[i]);//printing the character of the string..
 }
}
Output:-
abcdefg
gfedcba
Step-by-step explanation:
I have used strlen function that will be used after including the string.h header file.It returns the length of the string.After finding the last index I have iterated over the c string in reverse order and printing the character of the string one by one.
