Program in C
Here is the source code of the C Program to Check if a string contains at least one Number(digit) or not.
Code:
#include<stdio.h>
#include<string.h>
main()
{
int count=0,in;
char str[100]={0};
printf("Enter your String:");
gets(str);
for(in=0;in<strlen(str);in++)
{
if(str[in] >= '0' && str[in] <= '9')
{
count++;
}
}
if(count>=1)
printf("String contains at least one digits.");
else
printf("String does not contain at least one digits.");
}
Enter your String:csinfo
String does not contain at least one digits.
Program in C++
Here is the source code of the C++ Program to Check if a string contains at least one Number(digit) or not.
Code:
#include<iostream>
#include <cstring>
using namespace std;
main()
{
int count=0,in;
string str;
cout<<"Enter your String:";
getline(cin,str);
int len=0;
for(in=0;str[in]!='\0';in++)
{
len++;
}
for(in=0;in<len;in++)
{
if(str[in] >= '0' && str[in] <= '9')
{
count++;
}
}
if(count>=1)
cout<<"String contains at least one digits.";
else
cout<<"String does not contains any digits.";
}
Enter your String:csinfo360
String contains at least one digits.
Program in Java
Here is the source code of the Java Program to Check if a string contains at least one Number(digit) or not.
Code:
import java.util.Scanner;
public class AtLeastOneDigits {
public static void main(String[] args) {
Scanner cs=new Scanner(System.in);
String str;
int count=0,in;
System.out.println("Enter your String:");
str=cs.nextLine();
for(in=0;in<str.length();in++)
{
if(str.charAt(in) >= '0' && str.charAt(in) <= '9')
{
count++;
}
}
if(count>=1)
System.out.print("String contains at least one digits.");
else
System.out.print("String does not contain at least one digits.");
cs.close();
}
}
Enter your String:
csinfo360.com
String contains at least one digits.
Program in Python

for inn in range(0,len(str)):
if str[inn] >= '0' and str[inn] <= '9':
count+=1
if count>=1:
print("String contains at least one digits.")
else:
print("String does not contains at least one digits.")
