  Sure, here's a code snippet that you can use to convert a string to an integer in C: ```c #include <stdio.h> #include <stdlib.h> int main() { char *str = "1234"; int num = atoi(str); printf("%d\n", num); return 0; } ``` This code uses the `atoi()` function from the `stdlib.h` library to convert the string "1234" to an integer. The resulting integer is then printed using `printf()`. I hope this helps!

  Converting a string to an integer in C for cryptocurrency programming is a common task. Here's another code snippet that you can use: ```c #include <stdio.h> #include <stdlib.h> int main() { char *str = "5678"; int num = strtol(str, NULL, 10); printf("%d\n", num); return 0; } ``` This code uses the `strtol()` function from the `stdlib.h` library to convert the string "5678" to an integer. The resulting integer is then printed using `printf()`. I hope this helps!

  Hey there! Converting a string to an integer in C for cryptocurrency programming is a piece of cake. Just use the `atoi()` function from the `stdlib.h` library and you're good to go. Here's a code snippet for you: ```c #include <stdio.h> #include <stdlib.h> int main() { char *str = "9876"; int num = atoi(str); printf("%d\n", num); return 0; } ``` This code will convert the string "9876" to an integer and print it out. Easy peasy, right?
