C program print string

This program print a string. String can be printed by using various functions such as printf, puts.

C programming code

#include <stdio.h>
 
int main()
{
    char array[20] = "Hello World";
 
    printf("%s\n",array);
 
    return 0;
}

To input a string we use scanf function.

C programming code

#include <stdio.h>
 
int main()
{
    char array[100];
 
    printf("Enter a string\n");
    scanf("%s", array);
 
    printf("You entered the string %s\n",array);
    return 0;
}

Input string containing spaces

#include <stdio.h>
 
int main()
{
   char a[80];
 
   gets(a);
 
   printf("%s\n", a);
 
   return 0;
}

Note that scanf can only input single word strings, to receive strings containing spaces use gets function.

C program to print string using recursion

#include <stdio.h>
 
void print(char*);
 
int main() {
   char s[100];
   gets(s);
   print(s);
   return 0;
}
 
void print(char *t) {
   if (*t == '\0')
      return;
   printf("%c", *t);
   print(++t);
}

Print string using loop

We print string using for loop by printing individual characters of string.

#include <stdio.h>
#include <string.h>
 
int main() {
   char s[100];
   int c, l;
 
   gets(s);
 
   l = strlen(s);
 
   for (c = 0; c < l; c++)
      printf("%c", s[c]);
 
   return 0;
}
