Question

Write a program that receives a table of integers in a csv format (comma-separated values) from the standard input stream, and prints out the table of same values in a txt format (tab-delimited values) after:

converting the integers to their corresponding normalized scientific notations (using %e placeholder of printf function) and padding each value with a number of spaces at the RHS of the number so that the length of each table cell becomes 25 characters and the numerical value in each cell is left-aligned (Hint: use %-25e placeholder of printf function)

Answer 1

To convert a table of integers in csv format to txt format and express them in normalized scientific notation using C, you can use the printf function with the appropriate placeholders. The integers can be converted to scientific notation using the %e placeholder, and padded to a length of 25 characters with left alignment using the %-25e placeholder.

Step-by-step explanation:

In order to write a program that converts a table of integers from a csv format to a txt format and expresses the integers in normalized scientific notation, you can use the printf function in C. The %e placeholder can be used to convert the integers to scientific notation, while the %-25e placeholder can be used to left-align and pad each value to a length of 25 characters. Here is an example code snippet that demonstrates this:

#include <stdio.h>

int main() {
int num;

while (scanf("%d", &num) == 1) {
// Convert integer to scientific notation
printf("%-25e\\", (double) num);
}

return 0;
}
