Here is the code in C.
#include <stdio.h>
#include <string.h>
//main function
void main()
{
// character array to store the string
char str[1000];
int len,i,j;
char c,ch;
printf("Please Enter a string: ");
// read the string
gets(str);
// find the length of input string
len = strlen(str);
for(i=0;i<len;i++)
{
c=str[i];
// if any character of string is digit then it will check
// until it finds the next non-digit character
if(c>='0' && c<='9')
{
for(j=i;j<len;j++)
{
ch=str[j];
if(ch>='0' && ch<='9')
//print the number in the string
printf("%c",str[j]);
else
{
printf(" ");
i=j;
break;
}
}
}
}
}
Explanation:
First it ask user to input a string and store that string into character array.Then travers the array and find first digit character.If a digit is found then print that digit.After that in the inner for loop, check next character is digit or not, if a digit meets then print that digit.Repeat this until the next non-digit character founds.When a non-digit character meets print a space and update the value of "i" and break the inner loop.It will again check the same from the ith index in the character array.
Output:
Please Enter a string: The year has 365 days and the day has 12 hours
365 12
