Can Anyone Solve This Question In C Programming Language?

Hi,

 

Write code to solve the following problem. Define a function that takes a String as a parameter and returns an integer value. The function need to loop through each character in the input string to find a value of “x”. If a value of “x” is found in the string then return the position within the string where “x” is found else return -1.

Hi Stella,

 

Just a quick question about your problem. Is "x" a string or a character?

try this code to see if it is help ~~

#include <stdio.h>int findpos(char *str, char x);int main(int argc, char **args){[tab][/tab]char *s = "some gext";[tab][/tab]int r;[tab][/tab]r = findpos(s, 'g');[tab][/tab]printf("%d\n", r);}int findpos(char *str, char x){[tab][/tab]char *s = str;[tab][/tab]int i = 0;[tab][/tab]while (*s && (*s != x))[tab][/tab]{[tab][/tab][tab][/tab]++i; ++s;[tab][/tab]}[tab][/tab]return (*s) ? i : -1;}
