How can i store the result printed on output screen in c or c++ language??

Question

How to save output values in data types to use them again

Answer 1

You can replace printf() with snprintf() to store the formatted output in strings instead of printing to the console.

Answer 2

You couldn't get my point
Basically i made a program for infix to postfix expression conversion.
After printing the postfix expression on the output screen.
I want to use this result to evaluate this expression using real numbers.different functions of my programs print single values one by one in a randomised manner.
So i just simply want to store the output i get on the screen as a string in a char array instead of inserting values one by one in each function i made using array,queue or a stack.

Now u got my point??

Answer 3

Not so clear still..
If you can share that code, then I may give you a possible way..

You can use charecter array to store everytime a charecter result.. It depends on how you producing results...

Answer 4

Nikhil Sharma just before printing the value, just like Jayakrishna🇮🇳 said, store it in character array.

Answer 5

Nikhil Sharma this is an example what I mean.. This is what you're looking for..

#include<string.h>
#include<stdio.h>
int main()
{
char s[300];
int n=0;
for(int i=1; i<5; i++)
{ for(int j=1; j<5; j++)
{for(int k=1; k<5; k++)
{
s[n++]=(char)i;
s[n++]=(char)j;
s[n++]=(char)k;
printf("%d%d%d\n",i,j,k);
}
}
}

for(int i=0;i<strlen(s);i+=3)
printf("\n%d%d%d",s[i],s[i+1],s[i+2]);
return 0;
}

The last printf prints the same which is result of first 2 loop's produced result and displayed..

Answer 6

Can't you store the result in related data type variables before printing.. Are know about variable? If not, read about it..
Ex:
int a=3,b=5;
int c=a*b;
printf("%d", c);..

Answer 7

Like,output screen give me a new result which was not predictable or not supposed to present in the print statements.
So i wanted to save it in an array.
