  To convert a string to an integer in C, you can use the strtol() function from the standard library. Here's an example: ```c #include <stdio.h> #include <stdlib.h> int main() { char *str = "12345"; int value = (int) strtol(str, NULL, 10); printf("%d\n", value); return 0; } ``` This code will convert the string "12345" to the integer 12345. The third argument of strtol() specifies the base of the number system used in the string. In this case, we use base 10 for decimal numbers. You can replace "12345" with your cryptocurrency value string to convert it to an integer. strtol() also provides error handling by setting the endptr parameter to the first character that couldn't be converted. You can check the value of endptr to handle invalid input.
