Got it, let's break down why your current code is causing labels and values to split across lines, then walk through a few straightforward fixes.

Why Your Original Code Isn't Working #

Your current paste() call passes every label and numeric value as a separate argument, then uses sep='\n' to put a line break between every single argument. That means:

• "Student Id:" gets a line break after it, separating it from V1
• "Number of circuts:" gets a line break after it, separating it from V2
  And so on—exactly the issue you're seeing.

Solution 1: Combine Labels + Values First, Then Add Line Breaks #

The fix here is to first build each complete "label + value" pair as a single string, then join those pairs with line breaks using collapse='\n':

V1 <- 81
V2 <- 55
V3 <- 25

cat(paste(
  paste("Student Id:", V1),       # Builds "Student Id: 81"
  paste("Number of circuts:", V2), # Builds "Number of circuts: 55"
  paste("Time (Minutes):", V3),    # Builds "Time (Minutes): 25"
  collapse = '\n'                  # Joins the three strings with line breaks
))

This will output exactly what you want:

Student Id: 81
Number of circuts: 55
Time (Minutes): 25

Solution 2: Use sprintf() for Clean Formatting #

If you prefer a more concise approach, sprintf() lets you define a single template with placeholders for your values, and you can insert line breaks directly into the template:

V1 <- 81
V2 <- 55
V3 <- 25

cat(sprintf(
  "Student Id: %d\nNumber of circuts: %d\nTime (Minutes): %d",
  V1, V2, V3
))

Here, %d is a placeholder for integer values (use %f for decimals if needed), and \n adds the line breaks exactly where you want them.

Solution 3: Use the glue Package for Intuitive String Interpolation #

If you don't mind using a third-party package, glue makes string formatting super readable—you can just reference variables directly in the string and add line breaks naturally:

library(glue)

V1 <- 81
V2 <- 55
V3 <- 25

cat(glue("Student Id: {V1}
Number of circuts: {V2}
Time (Minutes): {V3}"))

No extra paste calls needed—just write the text exactly how you want it to appear, with {} wrapping your variables.
