Quick question regarding this issue, Why doesnt it print out the second value(converted second value
- by sil3nt
Quick question, What have I done wrong here. The purpose of this code is to get the input into a string, the input being "12 34", with a space in between the "12" and "32" and to convert and print the two separate numbers from an integer variable known as number. Why doesn't the second call to the function copyTemp, not produce the value 34?. I have an index_counter variable which keeps track of the string index and its meant to skip the 'space' character?? what have i done wrong?
thanks.
#include <stdio.h>
#include <string.h>
int index_counter = 0;
int number;
void copyTemp(char *expr,char *temp);
int main(){
char exprstn[80]; //as global?
char tempstr[80];
gets(exprstn);
copyTemp(exprstn,tempstr);
printf("Expression: %s\n",exprstn);
printf("Temporary: %s\n",tempstr);
printf("number is: %d\n",number);
copyTemp(exprstn,tempstr); //second call produces same output shouldnt it now produce 34 in the variable number?
printf("Expression: %s\n",exprstn);
printf("Temporary: %s\n",tempstr);
printf("number is: %d\n",number);
return 0;
}
void copyTemp(char *expr,char *temp){
int i;
for(i = index_counter; expr[i] != '\0'; i++){
if (expr[i] == '0'){
temp[i] = expr[i];
}
if (expr[i] == '1'){
temp[i] = expr[i];
}
if (expr[i] == '2'){
temp[i] = expr[i];
}
if (expr[i] == '3'){
temp[i] = expr[i];
}
if (expr[i] == '4'){
temp[i] = expr[i];
}
if (expr[i] == '5'){
temp[i] = expr[i];
}
if (expr[i] == '6'){
temp[i] = expr[i];
}
if (expr[i] == '7'){
temp[i] = expr[i];
}
if (expr[i] == '8'){
temp[i] = expr[i];
}
if (expr[i] == '9'){
temp[i] = expr[i];
}
if (expr[i] == ' '){
temp[i] = '\0';
sscanf(temp,"%d",&number);
index_counter = i+1; //skips?
}
}
// is this included here? temp[i] = '\0';
}
