  • Question
  • Does there any function exist to convert the int or float to a string?


  • Options
  • A. Yes
  • B. No

  • Correct Answer
  • Yes 

    Explanation
    1. itoa() converts an integer to a string.
    2. ltoa() converts a long to a string.
    3. ultoa() converts an unsigned long to a string.
    4. sprintf() sends formatted output to a string, so it can be used to convert any type of values to string type.

    #include<stdio.h>
    #include<stdlib.h>
    
    int main(void)
    {
       int   num1 = 12345;
       float num2 = 5.12;
       char str1[20];
       char str2[20];
    
       itoa(num1, str1, 10); /* 10 radix value */
       printf("integer = %d string = %s \n", num1, str1);
    
       sprintf(str2, "%f", num2);
       printf("float = %f string = %s", num2, str2);
    
       return 0;
    }
    
    // Output:
    // integer = 12345 string = 12345
    // float = 5.120000 string = 5.120000
