Program to Replace all 0’s with 1 in a given integer
Here we will discuss how to replace all the 0’s with 1 in a given integer using C programming language.
The concept is simple, find the digits of the integer. Compare each digit with 0 if the digit is equal to 0 then replace it with 1. Construct the new integer with the replaced digits.
The program for Implement a C Program to replace all 0’s with 1 in a given integer as an input, all the 0’s in the number has to be replaced with 1.
Question can come like Way 1
Write a code to change all zero's as one's (0s as 1s) in a given number? ex: 120014 needs to be printed as 121114
Question can come like Way 2
implement a c program to replace all 0's with 1 in a given integer as an input, all the 0's in the number has to be replaced with 1.
Algorithm
- Take Input in num and initialize a variable num with with value 0
- If num is equals to zero then update the value of num2 to 1
- Iterate using a while loop until num is greater then 0
- For each iteration initialize a variable rem and store unit digit of num
- If rem equals to 0 then set rem to 1
- Set num to num divide by 10 & num2 equals to num2*10+rem
- Reverse and print num2
C code
Run
#include<stdio.h>
//main program
int main()
{
int num,num2=0;
printf("Enter number: ");
//user input
scanf("%d", &num);
//checking for 0 input
if(num == 0)
num2=1;
//converting 0 to 1
while(num>0)
{
int rem = num%10;
if(rem == 0)
rem = 1;
num = num/10;
num2=num2*10+rem;
}
num = 0 ; // Store the reverse of num2
while(num2>0){
int r = num2%10;
num= num*10 + r;
num2 /= 10;
}
//converted number
printf("Converted number is: %d" ,num);
return 0;
}
Output
Enter number: 900120678 Converted number is: 911121678

int main()
{
char str[18];
scanf(“%s”,str);
for(int i=0;str[i]!=’\0′;i++)
{
if(str[i]==’0′)
str[i]=’1′;
}
printf(“%s”,str);
}
Python Solution
a = str(int(input()))
print(int(a.replace(‘0′,’1’)))
can we use array instead???????
#include
int main ()
{
int N[7];
for (int i = 0; i < 7; i++)
{
scanf ("%d", &N[i]);
}
for (int i = 0; i < 7; i++)
{
if (N[i] == 0)
N[i] = 1;
}
for (int i = 0; i < 7; i++)
{
printf("%d", N[i]);
}
return 0;
}
#include
using namespace std;
int main(){
int n;
cin >> n;
int m{0};
int i = 1;
while(n != 0){
int digit = n%10;
if (digit == 0) digit = 1;
m = m + digit*i;
i = i*10;
n = n/10;
}
cout << m << endl;
}
using namespace std;
int main()
{
int x,y;
cin>>x;
int rem,i,bin;
int sum;
sum=0;i=1;
while(x!=0)
{
rem=x%10;
if(rem==0)
{
rem=1;
}
sum=sum+rem*i;
i=i*10;;
x=x/10;
}
cout<<sum;
return 0;
}
Thanks for contributing the code Kavita
def replaces(num):
if (num==0):
return 0
#check last digit
digit = num%10
if (digit==0):
digit = 1
#else:
return replaces(num//10)*10 + digit
num = int(input(‘enter number: ‘))
print(‘result are: ‘ , replaces(num))
