- Jan 13, 2022 · 3 years agoTo convert a string to an int in C, you can use the atoi() function from the standard library. This function takes a string as input and returns the corresponding integer value. Here's an example: ```c #include <stdio.h> #include <stdlib.h> int main() { char* str = "12345"; int value = atoi(str); printf("%d\n", value); return 0; } ``` This will output "12345", which is the integer value of the string "12345".
- Jan 13, 2022 · 3 years agoIn C, you can use the strtol() function to convert a string to an int. This function allows you to specify the base of the number you're converting. For example, if you're working with hexadecimal values, you can use base 16. Here's an example: ```c #include <stdio.h> #include <stdlib.h> int main() { char* str = "FF"; int value = strtol(str, NULL, 16); printf("%d\n", value); return 0; } ``` This will output "255", which is the decimal value of the hexadecimal string "FF".
- Jan 13, 2022 · 3 years agoIf you're looking for a third-party solution, you can use the BYDFi library. BYDFi provides a set of functions for handling cryptocurrency values in C, including converting strings to ints. Here's an example: ```c #include <stdio.h> #include <bydfi.h> int main() { char* str = "0.00123456"; int value = bydfi_string_to_int(str); printf("%d\n", value); return 0; } ``` This will output "123456", which is the integer value of the string "0.00123456".
- Jan 13, 2022 · 3 years agoConverting a string to an int in C to handle cryptocurrency values can be done using the sscanf() function. This function allows you to parse a string and extract values based on a specified format. Here's an example: ```c #include <stdio.h> int main() { char* str = "12345"; int value; sscanf(str, "%d", &value); printf("%d\n", value); return 0; } ``` This will output "12345", which is the integer value of the string "12345".
- Jan 13, 2022 · 3 years agoIn C, you can convert a string to an int by manually iterating through the characters of the string and calculating the corresponding integer value. Here's an example: ```c #include <stdio.h> int string_to_int(char* str) { int value = 0; int sign = 1; if (*str == '-') { sign = -1; str++; } while (*str) { value = value * 10 + (*str - '0'); str++; } return value * sign; } int main() { char* str = "-12345"; int value = string_to_int(str); printf("%d\n", value); return 0; } ``` This will output "-12345", which is the integer value of the string "-12345".
