Print All Integers in a String[edit]
Swift[edit]
var line : String?
repeat {
line = readLine()
if let text = line {
for character in text {
if ("0" ... "9").contains(character) {
print(character)
}
}
}
} while line != nil
Python[edit]
string = input()
for char in string:
if char.isdigit():
print(char)
Java[edit]
int x = 24
C[edit]
#include <stdio.h>
#include <ctype.h>
#include <string.h>
int main( void ) {
char *line;
fgets(line, 255, stdin);
size_t line_length = strlen(line);
for (size_t i = 0; i < line_length; i++) {
if (isdigit(line[i])) {
printf("%c\n",line[i]);
}
}
return 0;
