Write a recursive function to convert a character string of digits to an integer. Example:
convert(“1234―) returns 1234. Hint: To convert a character to a number, subtract the
ASCII value ‘0’ from the character. For example, if the string s has only one character,
then the function can return the value s[0] – ‘0’.
Solution
#include<stdio.h>
int strToInt(char[] );
int main(){
char str[10];
int Value;
printf("Enter any integer as a string: ");
scanf("%s",str);
Value = strToInt(str);
printf("Equivalent integer value: %d",Value);
return 0;
}
int strToInt(char str[]){
int i=0,sum=0;
while(str[i]!='0'){
if(str[i]< 48 || str[i] > 57){
printf("Unable to convert it into integer. ");
return 0;
}
else{
sum = sum*10 + (str[i] - 48);
i++;
}
}
return sum;
}
