How would you write a program that takes a string of characters and reverses them in the C programming language?

Answer 1

void main()

{char a[30] = "India";

//Let the string be stored in a[30];

char b[30]; //declaring another string

for(i=0;i<strlen(a);i++)

{b[strlen(a)-1 - i]=a[i];}

//Now reverse string is stored in b;

//to print it

cout<<b;

getch();

}

Answer 2

#include <stdio.h>

main ()

{

int i=0,k=0,j;

char a[30],b[30];

printf("\nEnter the string:\n");

gets(a);

while(a[i++]!='\0')

k++;

for (i = 0,j=k-1; i <k,j>=0 ; i++,j--)

b[i] = a[j];

printf("%s",b);

return(0);

}

Answer 3

Parse the string, word by word, left-to-right, pushing each word onto a stack. When you reach the end of the string, clear it (make it empty), then begin popping words from the stack and appending them to the string. When the stack is empty, the words in the string will be in the reverse order.

Answer 4

I'd use a simple loop.
